    Arc'teryx - Men's Gamma Rock Pant

    Lightweight, breathable, technical alpine pant constructed with two weights of stretchy yet durable textile that provide enhanced abrasion resistance and mobility.

    The "skinny jean" look isn't my favorite, and you can't wear boots that easily. But if your climbing they are purrrfect and the form fit makes sense then. Plenty of brush wadding in these and not a scratch. OK in rain, you'll get wet, but they dry fairly quickly.

    Purrrfect indeed!

    unusual that Arcteryx actually made these larger and fit better than last years model------I bought XXL for 40 waist and they fit fine---even an ex soccer player like me can wear them---big enough in seat and legs------will use them in Ireland

    Perfect Minimalist Climb/Hiking/MTN Pant

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: Runs small
    • Size Bought: Large/Long

    These pants are nice.... real nice.

    I have added them to my warm weather hiking/mtn kit. If temps drop adding a base layer does wonders. They are very close to the Gamma AR pants but fit better in the legs and are a bit lighter.

    I think they run a bit small. I usually wear a 34/34 and has to get a Large/Long in these to fit. I wear a medium regular in the Gamma AR as those fit large.

    If your considering these pants for 3 season climbing, hiking, or warm mountaineering soft shell for your layer system you won't go wrong.

    Love these pants, now have 3 pairs and wear them pretty much every day.

    If you plan to invest in only one pair that will cover a variety of activities, please think about these ones. Although it's designed for rock climbing, I also wear them to play around doing other activities besides rock climbing...

    They fit perfectly—not baggy as other pants, easy to clean, dry fast due to the material, and the buckle is also stylish.

    Please, ask anyone at and they will help you out with size and all that. Or, if in doubt, perhaps order two different sizes and try them on before shipping back the one that doesn't fit well.

    Great Quality!

      I don't use the pants as what they're supposed to be meant for. I live in Maryland & lately it's been raining a lot because of that hurricane. It's doesn't let any rain pass through. Really nice quality. I'm 5'10, 150 lbs, and a small/regular fits perfectly fine. Don't hesitate to buy this great item! Couldn't have spent my moneu any better!

      I was looking for a good fit and length with solid construction. Have used it for cross country skiing and plan to test it on the rocks in the summer. Overall great pants for the outdoors .. you won't be disappointed.

      Most comfortable pant I own

      • Familiarity: I've used it several times
      • Fit: True to size

      I don't climb, I use these as a ski mid/base layer under my ski pant. Easy to take off the outer pant and have these below for walking around/driving etc. They are a very tight fit over my ski boots (dalbello KR2) but with the hook they would stay on. No edge guards though. Would make a nice touring pant on a warm day.

      The temperature regulation is absolutely perfect. They are very lightweight yet insulate well.

      I'm a 32/33 waist and the M is just right with an extra inch or so of stretch, tight with the belt cinched.

      Owl Rock and Rock Guide pants

      Arcteryx Rock Guide pants. I am very happy with them, after some OW, and desert climbing. Very stretchy, close technical fit ( more than Gamma LT), and the burly fabric areas are actually VERY durable, and still have a lot of stretch. GREAT belt system that stays put and is super easy to adjust. Not cheap, but worth the $$ if looking for a lightweight technical fit.

      Best pants ever made

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      I've used these pants for just about everything and they are amazing. As rock climbing pants they are about as good as it gets. The reinforced knees and butt fabric are extremely tough and there is a great overall flex to the fabric. These pants are also perfect for hiking because they are very breathable but also water resistant. I've been through a couple heavy down pours in these pants and they exceeded my expectations. Super light, very packable, easy to clean and my girlfriend says my butt looks great in them. They are my go to pants for just about anything right now and I dont think that will change. I have not tried them skiing yet but because of the stretchable fabric, I think they would be able to go over ski boots. But layer up cause they are definitely a minimalist style winter outerwear. The black pants can get pretty warm so if you plan to do a lot of summer activities I would suggest going grey.

      Alpine awesomeness

      • Familiarity: I've put it through the wringer
      • Fit: Runs small

      This pants is perfectly designed for alpine sessions. Gussetted crotch, stretchy and durable knees, lace hooks, minimalist pockets. I climbed a bunch of alpine routes in these and was super excited about how perfect they were.

      They do fit small but that is what they are designed for, nothing extra to get caught while climbing. Very streamlined and legs are a little short

      The lace hooks are really awesome, keeping your feet dry on the approach, while stomping through rivers. If you are getting splashed not dunked that is.

      But they are more function than fashion.

      Alpine awesomeness

      Looking for an alpine climbing pant but something I can also use for super warm spring touring missions. Think they will fit over a tlt6? I know I won't have an issue with my LaSportiva Nepal!

      Great Pant for Cool Weather Rock

      • Familiarity: I've put it through the wringer
      • Fit: True to size

      These pants are just the ticket for cold or cool weather rock climbing. They've held up to abrasive Sierra Granite and slick varnished Red Rock Sandstone. They're a little short on me in a size M at 6' tall and 170lbs, but for climbing that's OK. If you're my size and you don't want high waters - size in a Md/tall.

      When the extended model (tall) will be available?



      You need to either use the live chat function or call directly to backcountry. That way they can see if any new shipments are available. There is a possibility they may not even be getting any new stock in until the F13 season starts shipping (aug/sep)

      Are you gonna get these Gamma Rock color Heron pants back in stock in a medium to medium/long?

      An update: Bought these, and they fit like flood pants, it's ridiculous. I'm guessing these are strictly for guys who climb mountains and need there ankles exposed for whatever reason.. I have no idea why there's a boot hook, these wouldn't even come close to being able to hook onto a boot, unless it's a commando boot. Also bought the Gamma SL Hybrid, and had a similar problem, but the SLhybrid pants were at least two inches longer in the leg, so it's not my long legs, these pants really are just short. Oh and they sag a lot under the ass, on the upper thigh.. I love a lot of arcteryx gear, really dislike all their pants.

      There's some great sizing information available on as well as the Arc'teryx website. Arc'teryx does offer Tall sizing in many of their pant styles, which might work better for you.

      I think they've updated the pant (bought mine spring 2015) and the length might be a bit longer now. I'm 6'1'' and I got the regular length (medium waist) and they fit perfectly.
