    Softshell and hardshell in all the right places.

    The Arc'teryx Men's Alpha Comp Pant combines the free-moving softshell that ice climbers want and the weatherproof protection that alpinists need. Three-layer, fully taped Gore-Tex panels protect the seat, leg fronts, and lower legs with guaranteed waterproof breathable protection. Water-resistant Fortius 1.0 softshell covers the waist, crotch, backs of each leg, and gussets with stretchy air permeability to keep you comfortably warm whether you're climbing or not.

    An e3D design with a gusseted construction makes sure you can move freely in the trim-fitting Alpha Comp. It also features an integrated webbing belt and adjustable cuffs for a secure fit. You can set each lower leg gusset in three positions: closed for crampons, middle for alpine boots, and completely open for ski boots. Keprotec hem adjusters ensure that your crampons don't cut up the lower legs, and the zippered thigh pocket is a perfect place for your GPS.

    Best pants

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size
    • Size Bought: medium

    Wore these pants during our push up to the summit of Amadablam very sturdy, the Grivel crampons did not punctured holes. Now I did wear one base layer, an around 6,400 did put on down pants over them, however I never felt being cold, it was just a precaution.

    Good Overall Pant, Not Best for Cold

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size

    I purchased a medium, and the fit was true to size. The cuffs fits nicely over boots and are reinforced in appropriate areas. The legs flex well and allow a comfortable range of motion. While the pants are light and breath well, I would probably not rely on them in a very cold environment. The leg pocket was functional with easy access while wearing a harness. These pants provided good protection from plenty of wet snow and rain.

    Worked well on Kilimanjaro!

    I used these pants on the summit day of Mt. Kilimanjaro. I am a 5'7", 175 lbs. These worked very well to keep me warm and were very flexible, comfortable.

    So Nice!

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size

    These pants have such a great range of motion that make my ice climbing days that much better. The reinforced cuff seems very durable to deflect the inevitable crampon scrape. I've used the pants on a full day of ice climbing and a couple days of ski touring. It's been a great pant for these higher aerobic output activities.

    Nice material, strange fit

      The appeal is minimalistic design/features. The flaw is this extra bit of material between the waist and the seat that created a bubble that made an awkward fit and feel. Returned without using.

      Totally agree. The bubble-butt was a deal-breaker. Everything about the pants was awesome except that MAJOR issue. Side zip vents would be nice too. You can never have too many venting options...I also returned without using...

      decent, but definitely not my favorite

      • Familiarity: I've used it several times
      • Fit: Runs large

      These aren't the most durable or insulating pants I've used - they are light, but I'd want something at least a little more substantive for the price.

      The other problem is that these pants seem to be cut really long... since they don't have an inseam choice, I think they cut it long for versatility, but really it's just annoying.

      Light weight and Mega breathable

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

      I have used these pants several times now and overall i enjoy them.

      THe combo hard/ soft shell construction is very versatile, protection of the Gore Pro Shell in areas where you need it, seat, and front of the legs. WHile the soft shell lets your legs breath and not work up a sweat. I have used them rock climbing, skiing, and alpine climbing so far. My only dislikes is the pocket, and they are not great in cold weather, you really need a warm base layer in colder temps. I have some concerns with the durability of the soft shell fabric as it feels pretty thin.. time will tell. Over all I am happy with my purchase and would likely buy them again.

      Great pants, poor pocket

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

      I love these pants. They have the quality I've come to expect from Arc'tyrex. They are light, very comfortable and they are very flexible. Coming down I was in a lot of sun, they didn't get hot or wet. These really should get 5 stars but the pocket location is not good. If you put anything with any weight in it constantly hits your knee. The bottom of the pocket needs to come up 2 or 3 inches.

      Good pant for winter mountaineering

      • Familiarity: I've used it once or twice and have initial impressions
      • Fit: True to size

      Just bought it for my Mount Washington ascent in February. Fits good with my mountaineering boots. I'm 5,8'' 175 lbs with 33/34 waist. The size M fits perfectly. A nice base layer bottom underneath the pant is enough for most cold weather situations.

      Unanswered Question

      How do these perform for summer pants in drizzling rain? I live in SE Alaska and will be mostly hiking/hunting steep mountains in warm weather with intermittent drizzling rain. I also need to bust through a lot of brush which usually soaks the lower legs and front of upper thighs. I am worried that the gore-tex panels will be overkill when I'm not in the brush. Do the waterproof panels make a lot of noise and do they feel too stiff for hiking in nice weather?
