Best Overall Men's Climbing Pants

1. Black Diamond Alpine Light Pants ($130)

Material: 85% nylon, 15% elastane
Weight: 10.2 oz.
Pockets: 4 (1 zippered thigh)
What we like: Extremely durable, versatile, and comfortable design.
What we don’t: Pricey, not the most flattering fit.

The top award for this round-up was downright difficult to decide on—so we focused on the pants we grab the most. For a wide array of climbing objectives, the Black Diamond Alpine Light Pants are our daily drivers. They tick all the boxes, don't cost an arm and a leg, and are extremely comfortable to climb in. What more could you ask for? Don't let the "Alpine" name fool you. These are versatile, well-rounded trousers perfect for anything from light mountaineering to casual cragging in mild conditions. The beauty lies largely in these pants' simplicity—and durability. We've taken the Alpine Lights on a plethora of rowdy missions in the vertical—from big wall missions in Yosemite to multiday traverses in the alpine—and they keep on ticking. We wore them most recently on a two-day climb of the famous Cirque of the Towers Traverse in Wyoming's Wind River Range. They fended off some serious torture on this trip—from sharp granite chimney squeezes to surprise blizzards mid-pitch—and came out the other end with zero tears or issues.

The feature set of these pants is simple but functional. A single zippered thigh pocket provides safe storage for a phone or small essentials and there are two front drop-in pockets—but only one rear pocket. We prefer to have two rear pockets (optimally with at least one zippered), but some appreciate this low-bulk design. CordLock adjustable cuffs allow you to easily roll the pants up and fasten them in place, and an easy-to-use integrated webbing belt helps dial in the fit. At 10.2 ounces they aren't the lightest on this list, but are impressively compact and packable and boast stellar durability that seems to contradict the thin fabric. The single-weave, four-way stretch fabric affords a good deal of stretch without feeling too loose, and a minimal DWR treatment fends off light moisture. All told, this is a streamlined design that gets the job done. For many, that's all you need in climbing pants—but some may prefer a more specced-out silhouette. Also, while we love the versatility and function of the Alpine Light, it has a pretty baggy cut (which isn't our favorite), meaning it's not the most stylish pick for use around town. This may be low on the priority list for many, but is one of our biggest dings. Aside from the fit, however, these are just about the perfect climbing pants.

Best Budget Men's Climbing Pants

2. La Sportiva Roots Pants ($79)

Material: 97% organic cotton, 3% elastane
Weight: 8.6 oz.
Pockets: 3 (0 zippered)
What we like: Comfortable, lightweight, and functional design at an affordable price.
What we don’t: Basic feature set, no zippers, cotton isn't as breathable or durable as other fabrics.

It's rare that our best budget pick is simultaneously a contender for the best overall and most comfortable awards—but here we are. The moment we slid La Sportiva's Roots Pants from the box, we knew we were smitten. They fit perfectly, have a cozy, jogger-like silhouette, and boast impressive durability in spite of the light weight. The headliner for us is the Roots Pants' fit. With a wide perforated elastic waistband, soft fabric, slim tapered cut, and articulated knees, we find ourselves lounging around in these just as much as climbing. The waistband doesn't bunch up under a harness, and a dose of elastane baked into the fabric gives it the perfect amount of stretch for dynamic movement. Whether you're sending hard on steep sport climbs, or moseying around a boulder field—the Roots pants are the tool for the job. 

While these pants are go-to picks for us, the budget price comes with some downsides. Most notably, a minimal feature set. The low-profile waistband forgoes a drawstring to shave weight but makes it harder to dial in a fit—especially once the elastic starts to wear out. We also feel limited with only three pockets and wish La Sportiva had included at least one zippered pocket—a key feature we look for in climbing pants. That said, the simple lightweight construction may be just what some climbers are after (especially boulderers). We did find that the Roots hold on to wrinkles more than many, and the cotton construction is cozy but isn't as breathable as other pants on this list—something to consider on particularly hot, muggy cragging days or long approaches. In the end, the Roots Pants may not offer all the goodies of other premium models, but at $79, we'd say you get one heck of a send-ready package from a time-tested and reputable brand.

Best Alpine Climbing Pants

3. Arc'teryx Gamma Pants ($200) 

Material: 88% nylon, 12% elastane
Weight: 13.4 oz.
Pockets: 3 (all zippered)
What we like: Great durability, breathability, and weather resistance.
What we don’t: Expensive; not the lightest; no rear pockets.

Alpine climbing demands a lot from your gear, and Arc’teryx’s Gamma Pants deliver in just about every way. Built from a premium softshell fabric with a trim articulated fit, the Gamma is purpose-built for big objectives in the high country. The burly nylon shell resists abrasion from rock and ice, while a healthy dose of elastane (12%) and a gusseted crotch keep mobility high for delicate footwork and high steps. Fortius DW 2.0 softshell fabric in specific areas provides a boost in durability, weather resistance, and stretch. Unlike many softshell designs, the Gamma is impressively breathable and air-permeable, making it a fantastic choice for high-output ascents. Plus, a DWR finish and wind-resistant construction provide enough protection to fend off light precipitation and alpine gusts—perfect for unpredictable mountain weather. These were our pants of choice for a recent alpine mission in Nepal, which involved significant hiking to remote peaks.

It's important to note that these are not waterproof hardshell pants for serious high-altitude pursuits (one of our favorite pairs in this category is the La Sportiva Supercouloir GTX Pro Pant). Rather, these are durable, versatile, and breathable trousers that excel on long approaches and alpine climbs in favorable weather. What truly sets the Gamma apart is its alpine-ready feature set. The built-in webbing belt ensures a secure fit under a harness, and the tapered lower legs prevent snagging on crampons or gear. The cuffs also close with drawstrings, and the pockets are smartly placed—two zippered hand pockets and a handy zippered thigh pocket keep essentials secure without interfering with movement (though we wish Arc'teryx had also included rear pockets). And despite its softshell build, the Gamma remains lightweight and packable, making it a great choice for fast-and-light missions where every ounce counts. This isn't the most insulated option out there (layering underneath is key for frigid temps) and falls on the heavier end of the spectrum at 13.4 ounces, but for summer ascents and shoulder-season objectives, the Arc’teryx Gamma is hard to beat.

Best Sport Climbing Pants

4. La Sportiva Talus Pant ($109)

Material: 94% recycled polyamide, 6% elastane
Weight: 13.8 oz.
Pockets: 5 (0 zippered)
What we like: Comfy, durable, flexible fabric with a climbing-specific feature set.
What we don’t: No zippered pockets, no pull cord at cuffs.

Leave it to La Sportiva to keep the innovation train chugging along. In an increasingly saturated market, this time-tested, born-in-the-mountains brand just doesn't disappoint—and the Talus Pant is a perfect example. Uniquely designed for climbing, the Talus boasts superior freedom of movement with articulated knees, an appropriately baggy fit, and stretchy polyamide/elastane fabric, with some fun extra features thrown in the mix. The elasticized waistband has an integrated drawstring that can double as a makeshift chalk bag loop at the center back waist—a helpful feature if you want to forego the bulky webbing that comes standard with most bags (or for long boulders that necessitate a mid-send chalk-up). The Talus also has a dedicated brush pocket on the thigh (big enough to hold an iPhone) with a small elastic band for keeping things in place. Finally, these pants are constructed with recycled fabric, a step towards greater sustainability that we appreciate.

In testing, these pants performed beautifully. The fabric is durable, but lightweight and breathable—perfect for toasty days at the crag. The flexible fabric makes kneebars, far-reaching heel hooks, and big throws a cinch, and the burly construction fends off some serious torture. But we do have a couple of dings against the design. We love having five pockets but wish at least one was zippered for safely hauling a phone or other essentials up long lines. Also, there is no pull cord at the cuffs, making it harder to keep the pants rolled up—something we do almost any time we're climbing. Finally, the fit is a smidge baggier than we prefer—but this is just a personal preference, as we lean toward more tapered fits across the board. All told, the cozy, durable, and flexible fabric, dialed-in feature set, and overall sleek styling make these our absolute favorite pants for sport climbing in any environment.

Best Climbing Pants for Bouldering

5. Mammut Massone Light Pants ($99)

Material: 96% polyamide, 4% spandex
Weight: 10.7 oz.
Pockets: 3 (1 rear zippered)
What we like: Roomy, breathable, and extremely comfy with a jogger-like cut.
What we don’t: May feel too baggy for some; not as durable as other options here.

When it comes to bouldering, freedom of movement is key, and Mammut’s Massone Light Pants delivers this in spades. Built from a lightweight yet durable stretch fabric with a generous cut, these pants allow for unrestricted heel hooks, high steps, and dynamic moves on the rock. The 4% spandex content, gusseted crotch, and articulated knees ensure they move effortlessly with your body, while the lightweight build helps keep things breezy on warm days at the crag. Mammut also threw in a stretch waistband with an integrated drawstring, allowing for a secure fit without feeling restrictive. Combined with the elastic cuffs, these pants have a jogger vibe to them, making them a cozy option for just lounging around on lazy rest days. Whether you're sessioning at the gym or projecting an outdoor problem, the Massone Light is made to move.

That said, they’re not perfect. The lightweight build, while great for breathability, comes at the cost of some durability—abrasive rock will take its toll faster than with burlier options like the Arc’teryx Gamma. Still, they have surprised us with their durability. The looser fit, while comfortable, may also feel baggy for those who prefer a more streamlined silhouette. And finally, the pocket layout is minimal: the two hand pockets are useful, but the single rear pocket doesn’t add much in the way of functionality (though we do appreciate the zippered closure). Overall, for dedicated boulderers who prioritize mobility, comfort, and breathability, the Mammut Massone Light is an excellent pick that won’t hold you back when you're gunning for the send.

Best Crossover Climbing Pants

6. Teren Lightweight Traveler Pants ($130)

Material: 88% nylon, 12% spandex
Weight: 11.0 oz.
Pockets: 6 (3 zippered)
What we like: Stretchy, durable, antimicrobial, and breathable performance fabric with a stylish look; tons of zip pockets.
What we don’t: Magnet at waist can feel uncomfortable under certain climbing harnesses; no pull cord at the cuffs.

In our increasingly busy schedules, the ability to transition straight from the office to the crag is more important than ever. Demand for pants with sleek styling as business casual attire, coupled with outdoor chops for climbing and hiking after work has skyrocketed—and brands like Chattanooga-based Teren have risen to the challenge. With a slim, tapered silhouette, subtle branding, muted colorways, and discrete features, they look great around town—but peek under the hood, and you'll also find a seriously durable, adventure-ready design. The nylon, spandex blend is stretchy, wrinkle-resistant, antimicrobial, breathable, and extremely durable. We've worn these pants on all-day multi-pitch romps, up sharp sandstone chimney squeezes, and even as trekking pants on long thru-hikes across the country. In short, we've thoroughly put the Traveler Pant through the wringer—and they're still going strong. Send hard on the wall then hop downtown for a fancy date, these make transitions from back to frontcountry a cinch.

Features like three invisible zipper pockets, a silicone grip waistband, and hidden internal drawstrings allow you to strike a perfect fit and keep essentials at hand. The Traveler has more zippered pockets than most climbing pants we tested, a boon for safely toting phones, keys, etc. up long climbs without dropping them. They also feature the most unique button closure we've seen on any pants: a high-strength magnet that keeps the pants buttoned when you’re moving yet splays open when seated to allow for additional breathing room. We were skeptical at first but have ended up loving this design. Paired with the pant's stretchy fabric, it makes dynamic movement while climbing or hiking a breeze—and for those wondering—it's completely TSA-approved and doesn't harm electronics. The magnet can feel a bit uncomfortable under certain climbing harnesses though, if positioned wrong. While we have few quibbles with these pants, the design is very slim, which could be a turnoff for some climbers, though we personally don't feel restricted by the cut. Also, the fabric isn't quite as soft as other pants here. But, as stylish, streamlined chinos with chops for demanding vertical missions, these are perhaps the best crag-to-town crossover pants on the market.

Most Comfortable Men's Climbing Pants

7. Himali Equilibrium Stretch Pants ($95)

Material: 88% polyester, 12% spandex
Weight: 8.1 oz.
Pockets: 3 (all zippered)
What we like: Lightweight, breezy, and comfortable with a stylish cut and affordable price.
What we don’t: Not as durable as others, not great for colder temps, no pull cord at cuffs.

These are illegally comfy pants. The moment we slid them on, we knew they would not only be some of our favorite climbing pants, but perhaps our go-to loungewear as well. With a light and breezy polyester/spandex blend, the Himali Equilibrium's fabric is supremely comfortable and incredibly flexible—but the pants still feature a tapered, flattering cut. We've yet to find the extent of its stretch, even after throwing them on some of our more flexible friends. Stretchy heel hooks, massive dynos—you name it—no move can thwart these airy trousers. These are some of our favorite pants for hot summer sends, as they provide adequate durability on abrasive rock, yet also give something of a cooling effect with their breathable fabric and "barely there" feel. This is a boon for summer cragging, but it means the Equilibrium isn't the best choice for colder season climbs.

We also love the fit and pocket layout, with three zippered pockets for hauling essentials up the rock, and a slim tapered fit around the ankle for unhindered visibility during precise foot placements (a common complaint of ours with other flaring baggy climbing pants is not being able to see our feet). Still, while we love the ultralight design, it's not without its cons. The material has a bit of a shine to it—it "swishes" more than others when walking—so these aren't our favorite for use around town (unless we're going for a strictly casual look). That said, these double as great workout/crossfit pants, and we've read several reviews of users even running with them in cooler temps. Finally, while the thin fabric is key to the Equilibrium's breathability, we have some concerns about its long-term durability. We've had no issues so far—and our sample has fended off light abrasion on rough sandstone sport climbs—but these won't hold up to as much torture as thicker models like the Marmot Topanga below. In short, if comfort, weight, flexibility, and breathability are core concerns of yours at the crag or gym, look no further than these featherlight wonders.

Other Men's Climbing Pants We Love

8. Patagonia Venga Rock Pants ($109)

Material: 93% Regenerative Organic Certified cotton, 7% spandex
Weight: 14.7 oz.
Pockets: 5 (1 zippered thigh)
What we like: Classic, relaxed cut in a comfortable design from a trusted brand.
What we don’t: Not as breathable or durable as other materials; on the heavy side.

For climbers who prefer a natural feel with plenty of stretch, the Patagonia Venga Rock Pants are a standout choice. Designed specifically for rock climbing, they blend organic cotton and spandex for a soft, breathable feel that doesn’t skimp on mobility. The gusseted crotch, articulated knees, and partially elasticized waistband provide a dialed-in, flexible fit that stays put under a harness. The fabric’s slight stretch ensures they move with you on high steps and far-reaching heel hooks, and the cuffs adjust with a unique low-profile shock cord and cord lock. Plus, Patagonia’s commitment to sustainable materials is always a bonus. True to Patagonia's ethos, the Venga Rock’s primarily organic cotton build is one of the more eco-friendly options on the market. We also dig the pocket layout of these pants, with two rear pockets (many climbing pants only offer one), and a zippered thigh pocket.

But like most cotton-heavy climbing pants, the Venga Rock isn’t without its trade-offs. Cotton absorbs moisture and dries slowly, making these less ideal for humid conditions or sweaty gym sessions. The fabric is also on the thinner side, which is great for comfort but less so for durability—abrasive off-widths and repeated kneebars will take their toll over time. And though the fit is generally well-executed, some might find the waist system unnecessary or finicky compared to a simple drawstring. The Venga is also a bit more flaring near the bottom than we like, while still feeling tight along the thigh. That said, for casual cragging and those who prioritize comfort above all else, the Venga Rock Pants are a classic pick that won’t feel out of place from the boulder field to the brewery.

9. Black Diamond Sequence Pants ($95)

Material: 100% polyester 
Weight: 10.9 oz.
Pockets: 3 (0 zippered, back pocket has a snap)
What we like: Comfortable and versatile for aggressive climbing or just lounging around.
What we don’t: Pretty baggy fit; we wish the back pocket was zippered, no pull cord at cuffs, no articulated knees or a gusseted crotch.

The Black Diamond Sequence Pants are a fantastic choice for climbers who prioritize comfort and versatility. Made from lightweight, stretch-woven ripstop fabric with a PFC-free DWR finish, these pants strike a great balance between breathability, durability, and mobility. The polyester fabric offers just the right amount of stretch for unrestricted movement on the wall, though we do find ourselves wishing for articulated knees and a gusseted crotch for a boost in mobility and comfort. With a minimalist yet functional design, the Sequence is equally at home on a multi-pitch climb, at the crag, or just lounging at camp. The waistband is lined with a soft fleece fabric, adding a nice touch of comfort and ensuring the pants stay put under a harness without pinching or shifting around.

That said, the Sequence Pants lean more towards casual than technical. They don’t have the ultra-burly durability of some heavier-duty climbing pants, making them less ideal for abrasive rock or gnarly off-widths. The ripstop fabric will fend off some light abuse, but they are better suited for more casual pursuits. Additionally, the straightforward design lacks the storage of more feature-rich options, with only two front hand pockets and a single rear snap pocket. We also wish the back pocket was zippered and that there were cinch cords at the cuff. Finally, these are a bit too baggy for our taste, with more flare at the ankle than we prefer because it tends to hinder our vision during precise foot placements unless the cuff is rolled up. In the end, for climbers seeking a lightweight, do-it-all pant that transitions seamlessly from the gym to the crag to everyday wear, the Sequence is a solid bet at an approachable price point from a time-tested brand—but we would point most climbers to Black Diamond's Alpine Light Pants above over these.

10. Prana Stretch Zion Standard Pant ($98)

Material: 97% nylon, 3% elastane
Weight: 11.2 oz.
Pockets: 5 (1 zippered thigh)
What we like: Thoughtful design with great stretch and features.
What we don’t: Seems to be a drop in quality and performance from previous iterations.

Ah, the legendary Stretch Zion. These were the first climbing pants our author owned—and he still romps around in his initial tattered pair to this day (purchased in 2016). Why hasn't he tossed this ancient iteration? They just don't make 'em like they used to. What was once our absolute favorite design for climbing, hiking, and all manner of outdoor activities, now just doesn't hold the same appeal. The fabric has changed, the fit is less dialed, and they seem to deteriorate faster than older versions. However—our personal nostalgia aside—these are still standout pants in the climbing community, and definitely worthy of praise. The Stretch Zion fabric is flexible but sturdy, and they still feature that signature dual-entry hip pocket we love so dearly (one zipper on the top, and one on the side). This allows you to quickly snatch your phone or other essentials from any angle mid-climb.

We also appreciate the adjustable webbing waistband with a tension lock, the snap roll-up feature at the cuff, and the ventilated inseam gusset. On paper, these are stellar pants—but we struggle to love the current fit and feel. They are quite baggy with heavy flaring at the ankle, impeding our vision during delicate footwork (they are, however, offered in a slim version). We also feel like the fabric pills faster than older iterations (ours started after just a few washes) and we have noticed a drop in quality (in line with many other user reviews). By contrast, our 2016 pair has zero pilling spots and only one small rip to speak of after easily over 100 pitches of hard climbing. We're pretty bummed because these were, hands down, our do-everything pants, but that's the way it goes. The Stretch Zion still has a lot to offer and is relatively affordable (and often on sale), so we'll keep recommending them for the right climber. But diehard Prana fans be warned: They simply aren't the same pants we cherished years ago.

11. Mountain Hardwear Rockrydge Pant ($99)

Material: 67% cotton, 25% nylon, 8% elastane
Weight: 6.7 oz. 
Pockets: 4 (1 back zippered)
What we like: Comfy; lightweight; thoughtfully designed with subtle styling for use around town.
What we don’t: Fit seems to run large; thin cotton blend isn't as durable as others.

The Mountain Hardwear Rockrydge Pant is a versatile option that seamlessly transitions from the crag to casual settings. Crafted from a blend of cotton, nylon, and elastane, these pants offer a comfortable feel with added durability and stretch, catering to climbers' needs for both mobility and resilience. The elastic waistband, complemented by an adjustable webbing belt, ensures a secure and customizable fit, while the cinchable cuffs allow for adaptability during climbs. The inclusion of multiple pockets, including a zippered back pocket and a drop-in thigh pocket, provides practical storage solutions for essentials like a phone or climbing tools. While the fit is a bit too baggy for our taste, these have a sleek enough look to them that we find ourselves rocking them around town as casual office chinos. And, with the pull cord at the cuffs, you can easily roll them out of the way for clear views of precise footwork.

While these are undeniably comfy, the cotton-rich fabric won't dry as quickly as synthetic alternatives and isn't as breathable or durable. Despite the cotton blend, these are some of the lightest pants in our arsenal. But, while the thin design boosts breathability, it doesn't offer the same level of abrasion resistance as heavier-duty climbing pants, potentially affecting longevity in rugged environments. Despite these considerations, the Rockrydge Pant stands out for its blend of comfort, functionality, and style, making it a solid choice for climbers seeking versatility both on and off the rock.

12. Marmot Topanga Climbing Pants ($100)

Material: 66% cotton, 31% nylon, 3% elastane
Weight: 15.0 oz.
Pockets: 4 (1 back zippered)
What we like: Comfy, durable fabric; articulated knees and gusseted crotch for great mobility.
What we don’t: Fit runs large; no thigh phone pocket; heaviest pants we tested.

The Marmot Topanga Pants blend comfort and durability, making them a solid choice for climbers who want a pair of pants that can handle both gym sessions and outdoor projects. Made from a mix of cotton, nylon, and elastane, they offer a soft, breathable feel with enough stretch to accommodate dynamic movement on the wall. Articulated knees and a gusseted crotch enhance mobility, while the elastic waistband with a drawcord helps snag a secure fit. The pocket layout is nice, with one back zippered pocket, but we wish it had a thigh pocket for our phone—always a helpful touch when wearing a harness. We also appreciate the UPF 50 rating, which adds a layer of protection for long days under the sun.

The high cotton content makes the Topanga comfortable but also means they don’t dry as quickly (and aren't as breathable) as fully synthetic alternatives. Additionally, the regular fit may feel a bit too relaxed for climbers who prefer a more tapered or athletic cut. We also found that they run quite large. Our author wears a men's medium across the board, and these were much too long for his legs. He threw them on a taller friend who usually wears large, and they fit him perfectly (though they were a bit tight around the hips). Additionally, we had some issues with the pants riding down mid climb, even with the drawstring tied—unless you cinch it down quite tight it seems they struggle to stay up. Finally, these are the heaviest pants in our lineup, making them suboptimal for ultralight missions in the mountains. These qualms landed the Topanga at the bottom of our list. But, if you’re after a climbing pant that balances casual style with functional performance, this is a well-rounded option that won’t feel out of place at the crag or around town—if you can nail the fit.

About Our Testing Process

As the climbing community has exploded, so has the demand for innovative apparel for each discipline. Niche designs have surfaced for bouldering, sport and trad climbing, alpine missions, and high-altitude mountaineering—and it's important to know the difference between each style. To narrow in on the best climbing pants on the market, our climbing editor, Chris Carter, took countless pairs all over the world on as many varieties of climbs as possible to craft our list of 12 models above. A lover of big wall epics, alpine scrambles, and lazy evenings at local crags, Chris is based in the sandstone paradise of Chattanooga, TN, but spends a significant chunk of each year climbing all around the world. 

Throughout the testing process, these pants found themselves on alpine ascents in Nepal, big wall objectives in Yosemite, multi-pitch romps in Mexico, sport climbs in Kentucky, and even first ascent bids in East Africa. Key aspects such as durability, breathability, feature set, weight, and fit were considered before considering any pant—and each pant here had to excel in most, if not all, of these areas to merit any real estate above. Finally, we know the climbing pants market is constantly evolving. As a result, we keep our finger on the pulse of new products when they surface, adding standouts to our list along the way and ensuring our existing reviews stay up-to-date. Note: This guide focuses specifically on men's pants catered toward climbing. If you are looking for more trekking-oriented pants, be sure to check out our round-up of the best hiking pants.

Climbing Pant Categories

Different disciplines demand different features from climbing pants. Boulderers often prioritize durability and mobility, while speedy alpine climbers look for lightweight breathability. It's important to consider the type of climbing you plan to be doing most before landing on your steed of choice. Below are the core categories of climbing pants we tested, and some primary features of each camp. 
 

Bouldering/Gym
Bouldering has exploded in popularity, and we see more and more pants hitting the market tailored specifically for this discipline. Boulderers don't require all the specs, pockets, and zippers of other climbing pants, and tend to prioritize durability and flexibility over other features. Bouldering pants are often on the baggy side for unrestricted range of motion, and have a good deal of stretch to their fabric. We generally see a simple pocket layout on these pants, since you often aren't climbing a boulder with anything in your pocket. Also, bouldering generally involves more delicate, precise footwork than sport, trad, or alpine climbing. For that reason, we find it important to either be able to roll the pants up at the ankle or cinch them down tight with a pull cord at the cuff to give us an unrestricted view of our climbing shoes.
 

On the other hand, pants like the Mammut Massone Light have a jogger-like design with elasticated cuffs for easily spotting your feet. Finally, features like articulated knees and a gusseted crotch are important for enhanced mobility. In the same token, gym climbers often don't require an extensive feature set in their pants and probably won't be toting phones or other trinkets up the wall in zippered pockets. We tend to wear the same pants to the gym that we wear while bouldering outside. Our favorite pants in this category are the Mammut Massone Light (which does have one back zippered pocket), the La Sportiva Roots Pants, and the Black Diamond Sequence Pants. 
 

Sport, Trad, and Multipitch Climbing
Roped-up lead climbers (and topropers) may be on the hunt for a different set of features than their pebble-wrestling friends. Venturing into the vertical, we'll often carry a phone, climbing tape, or other small trinkets—which need to stay safe and secure hundreds of feet in the air. Thoughtfully placed zippered pockets are the main addition we look for in this category, preferably on the thigh. Carrying an iPhone in the back or hand pockets under a harness is downright unpleasant, and we find a zippered thigh pocket is the only way to comfortably climb with anything clunky. We also prefer these pants to have a good deal of stretch baked into the fabric and be adequately breathable for hotter cragging sessions. For that reason, we tend to gravitate to nylon, polyamide, or polyester blends instead of cotton blends, since they have solid durability, lighter weights, and better breathability.
 

Our favorite pants in this category are the La Sportiva Talus and Black Diamond Alpine Light. That said, we often grab some of our favorite cotton blended pants, such as the Mountain Hardwear Rockrydge (67% cotton, 25% nylon, 8% elastane) and La Sportiva Roots (97% organic cotton, 3% elastane) for sport climbing in shoulder-season conditions, given their comfort and stretch. While not as important as on bouldering pants, sport and trad climbs also often involve very precise footwork, so we appreciate when the cuffs can be cinched back with a pull cord or rolled up tight. Articulated knees and a gusseted crotch are also important features for this category (and really any climbing pant). All told, sport, trad, and multi-pitch rock climbers don't have to fuss as much about their pants as other athletes, but there are certain considerations that can make their disciplines more comfortable.
 

Alpine Climbing
Alpine climbing demands pants that balance durability, weather resistance, weight, and mobility. Unlike bouldering or sport climbing, where breathability and mobility are key, alpine pants need to withstand abrasive rock, shifting weather, and crampon strikes. That’s why most feature tough softshell fabrics, articulated knees, and a trim fit to reduce snagging. Zippered pockets secure essentials, while adjustable waists and cuffs ensure a dialed-in fit over mountaineering boots or approach shoes. Our top pick, the Arc'teryx Gamma Pant, excels with Fortius DW 2.0 softshell fabric, great stretch, and a well-balanced mix of breathability and weather protection. Other hardwearing options include the popular Outdoor Research Cirque Lite Pants ($139) and the waterproof Black Diamond Highline Stretch Pants ($269) for all-day mountain performance.
 

High-Altitude Mountaineering
Demanding pants with more weather resistance, durability, and all-around protection than those billed for fast and light alpine missions, high-altitude objectives take a serious toll on climbing apparel. Those pushing deep into the greater ranges—think 6,000 meters and up in the Karakorum or Himalayas—will want burly pants (often hardshell waterproof designs) that will keep your legs toasty and dry in sub-zero, snowy conditions. These pants often feature thicker fabrics, a plethora of pockets, zippered vents, reinforced lower legs, and flared bottoms for fitting over clunky mountaineering boots. Our favorite pants for these excursions are the La Sportiva's Supercouloir GTX Pro Pant ($549), a high-end technical hardshell pant designed specifically for extreme mountaineering missions, and the La Sportiva Bernina 3.0 Pant (discontinued) pictured below. For more casual climbs, we've also had great luck with Helly Hansen's cheaper Odin 9 Worlds Infinity Shell Pants ($425). In the end, those pushing close to the death zone need to carefully consider their clothing before venturing into high altitudes.
 

Fabric and Durability

The best climbing pants strike a careful balance between durability and mobility, and much of that comes down to fabric choice. The vast majority of options on our list utilize some blend of nylon, polyester, cotton, and elastane (spandex), each with its own strengths and weaknesses. Nylon is king when it comes to toughness—it shrugs off abrasive rock, resists tearing, and holds up well over time. You’ll find it in alpine-focused pants like the Arc’teryx Gamma and even the Black Diamond Alpine Light, where protection against harsh rock and the occasional run-in with a crampon is critical. Polyester, while slightly less durable than nylon, is lightweight, breathable, and wicks moisture well, making it a solid choice for high-output days.
 

Cotton, on the other hand, is beloved for its soft, broken-in feel but falls short in pure abrasion resistance. However, when blended with synthetics like in the Patagonia Venga Rock and Marmot Topanga, it offers a comfortable, stretchy feel without completely sacrificing durability. Lastly, elastane is the secret ingredient for mobility, giving pants the necessary flex for big moves on the rock. That said, durability ultimately comes down to fabric weight—heavier blends tend to last longer but can feel restrictive, while ultralight designs—like the Himali Equilibrium Stretch Pants—boost comfort and breathability at the expense of longevity. As with most climbing gear, there’s no perfect answer, and your ideal fabric mix will depend on where and how you climb. Those who venture onto big walls for multiple days—such as ascents of El Cap—should look for more durable, weather-resistant designs, whereas fast and light alpine climbers may opt for a lighter, more breathable pant for unrestricted movement.
 

Weight and Packability

Weight and packability matter when choosing climbing pants, especially for alpine missions or stuffing a backup pair in your pack. Some climbers, like boulderers, aren't as concerned with the weight of their pants, whereas sport or alpine climbers pushing the grade may consider how the extra weight is impacting their performance. In general, tougher fabrics translate to greater durability but come at the cost of extra bulk. Pants like the Arc’teryx Gamma, Patagonia Venga Rock Pants, and Black Diamond Sequence use thicker materials that can withstand sharp rock but take up more space and feel heavier during long days. On the other hand, ultralight options like the Himali Equilibrium Stretch Pants and Mountain Hardwear Rockrydge prioritize breathability and mobility, packing down small but sacrificing some durability. For most climbers, a middle ground is best—pants that are light enough to move freely but still tough enough for regular abuse. If fast-and-light is your style, go for a packable design, but if longevity is key, be ready to carry a bit extra weight.
 

Breathability 

When you're pulling hard on a route or hiking to the crag under a hot sun, breathability and ventilation can make or break your comfort. Climbing pants should dump heat efficiently while still offering enough protection from rough rock and the elements. Lightweight fabrics like nylon and polyester blends naturally breathe well, while thicker softshells often integrate zippered vents or mesh-lined pockets to boost airflow. For high-output climbing—whether it’s a sweaty gym session, a south-facing sport route, or a long alpine push—opting for a breathable, quick-drying pant is key. The ability to easily roll up your pant cuffs with a locking cinch cord is also a helpful feature for boosting airflow while climbing. Some pants, like the Prana Stretch Zion even add ventilated or perforated inseam gussets for a boost in A/C. The Mammut Massone Light and Himali Equilibrium Stretch (a much more breathable option) are great examples of airy bouldering pants, while the Arc’teryx Gamma balances ventilation with weather protection for alpine terrain.
 

Mobility

Mobility is everything in climbing pants—whether you're high-stepping on a techy sport route, heel-hooking on a boulder, or stemming wide in a dihedral, your pants need to move with you, not against you. The best designs achieve this with a strategic mix of fabric stretch, a gusseted crotch, and articulated knees, all of which allow for a full range of motion without restriction. Blended fabrics with elastane (spandex) offer the most give (like the 85% nylon/15% elastane Black Diamond Alpine Light Pants), while some pants, like the Black Diamond Sequence or Patagonia Venga, rely on a looser, baggy fit to boost mobility. Alpine-focused options like the Arc’teryx Gamma balance stretch with durability, ensuring you can move freely without worrying about snags or tears on rough terrain.
 

Key Features

Pockets
Pockets play a crucial role in the functionality of climbing pants, providing essential storage for gear, snacks, and personal items while you’re on the move. The various pocket layouts found in the climbing pants we reviewed reflect the different needs of climbers. One standout feature is the zippered thigh pocket, which is invaluable for safely carrying a phone during climbs, or a slim wallet on longer multipitch romps. Trying to stash items in the front hand pockets or back drop-in pockets under a harness is an unpleasant experience. A well-placed thigh pocket keeps your device secure and easily accessible under the leg loop of your climbing harness for quick route checks or capturing the moment of a send without the risk of it falling out or getting in the way. Our favorite thigh pocket is found on the Prana Stretch Zion Pants, which has a zipper on the top and side for quickly accessing its contents from any angle. A solid pocket layout can enhance your climbing experience, allowing you to focus on the rock rather than worrying about your gear.
 

Drawstring Ankle Cuffs 
As we have discussed several times above, it's common practice to roll up the cuffs of climbing pants for a boost in ventilation and to better view your climbing shoes for precise footwork. The last thing you want is an annoying chunk of fabric flapping around your shoes as you desperately stretch for that minuscule jib mid-crux. For this reason, climbing pants often have more of a flared bottom compared to travel or hiking pants, allowing you to easily roll them up your calf. Many pants also come with a low-profile shock cord and cord lock at the cuff, which helps cinch the fabric down and tuck it away. Our favorite pants, the Black Diamond Alpine Light, are just baggy enough around the ankle to easily roll them up our calves, and they also feature CordLock adjustable cuffs. 
 

Adjustable Waistband
Adjustable waistbands are a vital feature in climbing pants, ensuring a secure and customizable fit that adapts to your body and movements. There are two common types of closures: drawstring closures and adjustable webbing belts. A drawstring closure allows for easy quick adjustments and provides a comfortable, streamlined feel without adding bulk. However, some climbers (like this author) prefer the added security of an adjustable webbing belt, like the one found on the Arc'teryx Gamma Pants. This type of closure offers a more tailored, secure fit and can be fine-tuned for comfort. Additionally, webbing belts often distribute pressure more evenly across the waist, preventing pinching and discomfort during extended climbing sessions. Ultimately, the choice between drawstring and adjustable belt closures comes down to personal preference, but both options aim to enhance comfort and performance on the wall, keeping your pants where they need to be.
 

Sizing and Fit

Dialing in the right fit is key to all-day comfort at the crag. Too tight, and you’ll feel restricted on big moves; too loose, and you risk excess fabric catching on rock or gear. Most climbing pants fall into relaxed or athletic fits, with some, like the La Sportiva Roots and Teren Lightweight Traveler, offering a trimmer profile, while others, like the Mountain Hardwear Rockrydge and Marmot Topanga, run noticeably large. A well-tapered design ensures your cuffs don’t snag on footholds, and features like adjustable waistbands or drawstring cuffs let you fine-tune the fit. If you're between sizes or prefer a tailored look, it's worth checking user reviews—some pants have a roomier cut than expected, which can impact mobility and comfort on the wall. We tend to gravitate to a trimmer cut, as long as the fabric has solid stretch. Other climbers prefer a baggier fit for unrestricted movement and a boost in ventilation. 
 

Style vs. Function

Though we find this to be more of a consideration for hiking or travel pants, the balance between style and function/performance is an important element to keep in mind for some climbers. If you are packing for a climbing trip—and want to keep things light—it's helpful to have a few pairs of pants that can do it all, from the boulder field to the brewery. Pants that perform well on the wall but don't look slouchy around town are a boon for rest days, fancy dinner dates, or just lounging around camp mid climbing trip. We climbers aren't notorious for our high fashion, but that doesn't mean we have to always look like rugged dirtbags.
 

Many of the pants we tested above boast stellar outdoor climbing chops, with a slim fashionable silhouette for use around town. Our favorite crossover pant is the Teren Lightweight Traveler Pants. With a tapered fit and subtle feature set, they look like business casual chinos but feature durable, antimicrobial, and breathable performance fabric for active use. Models like the Patagonia Venga Rock Pants, Marmot Topanga Pants, and even the softshell Arc'teryx Gamma Pants have muted enough colorways and designs that won't look slouchy off the wall. In the end, it's nice to have a Swiss Army Knife pant that can hike, climb, and go out to dinner all in the same day.
 

Sustainability

To continue exploring and climbing around our beautiful planet, we must make conscious choices to protect the natural world. Purchasing climbing pants with sustainability in mind is a simple yet impactful step toward a greener future. We appreciate brands that prioritize eco-friendly practices, and one common approach in the climbing pant market is the use of recycled materials. Several options on our list incorporate recycled fabrics, such as the La Sportiva Talus Pant (94% recycled polyamide, 6% elastane). Also, the Patagonia Venga Rock Pants is made with 93% Regenerative Organic Certified cotton, which is an environmentally friendly method of producing cotton products. 
 

In addition to recycled and organic fabrics, keep on the lookout for other sustainability indicators, including Fair Trade certification, bluesign-approved materials, and PFAS-free DWR coatings. Traditional DWR finishes often contain harmful per- or polyfluorinated chemicals—known as "forever chemicals"—that pose risks to the environment. By choosing climbing gear that embraces these principles, you can feel good about your impact on the planet while enjoying your time outdoors.
