Unanswered Question

I saw these pants listed in the canyoneering article. Should I get these or the would the $300 Gamma MX pants be more appropriate for sliding through the McDonald's playpen covered in sandpaper?

I wear Levi's with a 31" waist and 34" length. Would a small-regular be the correct size to order? Pls advise.

Excellent pants

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

These pants are excellent. Perfect on a late winter hike up Old Rag Mountain in SNP: protected my legs during rock scrambles, blocked wind and chiil on the summit, but didn?t overheat once the late morning sun warmed things up heading back down. Hooks at leg openings were ideal to keep snow and rocks from getting in my boots. Used them a fair amount around the neighborhood during our seemingly endless winter in MD. Slight lining provided the right amount of warmth/protection from wind & cold while watching the kids sled but didn?t get my legs too warm while shoveling. Will be psyched to get them out more next winter. Pricey, but like all Arcteryx stuff solidly built to last.

I love pants.

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Height: 6' 3"
    Weight: 190 lbs
    Size Purchased: Medium

I love pants and these are some of the best pants I've ever put on.

Thick enough to resist all but the worst catclaw and underbrush you may encounter bushwacking or hiking. Breathable enough to shed some of that moisture on your approach. Warm enough for early winter ascents up mountains. Comfortable enough to rock for long days outside or running errands. Built in belt is awesome.

My only con is the gaiter style boot clip to keep the pant down catches on your shoelaces when you don't need it to (90% of the time I wear them)

I typically wear a Large in almost everything but I checked the size chart and I am a medium in these!

Awesome pant

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

I was a little worried about the waist size but I just exchange from XL Regular to L Small and that was the perfect desition. Definitely I recommend this pant to be use in any season. I did my first ascent with them in NH in winter with 2 fahrenheit degrees and works perfect. A lot of snow and many fallen but the pants still fine.

Awesome  pant

Just got back from a 6 day expedition on Rainier. What are you waiting for? Buy. These. Pants. The Gamma AR's are my favorite piece of gear that I own. I lived in these things for the better part of 8 days straight and they held up exceptionally. Totally warm at 14,000+ feet at 5am in strong winds and breathable in 75 sun on the lower mountain when your getting absolutely cooked by sun coming off the glacier. I'm a 32/33 waist and the medium fit perfect. The pant has a super athletic cut so they'll likely fit you great. Low profile, amazingly flexible breathable fabric. I'll be using these extensively in the White's over the next 6 months. I recommend these pants to anyone doing multi-day or even single day hiking or mountaineering. The perfect companion for your peak bagging adventures!

Great Hiking Pant

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

i am 6' 210lbs with a 34 waist and the L/Reg is a good fit. could be a little tighter. i tried the medium and the legs fit better but the waist was too tight.

i am a photographer and use these pants as my main hiking and excursion pant. i was out late at night at the beach and was taking some longer star images and wandered the beach and ended up walking into deep pools. the pants got soaked up to my calf but never absorbed any water. the DWR is great! the stretch on the fabric is also amazing. i have full range of movement and have never been in a spot that i thought the pants were restricting me.

the only downside is the pants are a bit noisy. could be that they are new.

Great pant

  • Familiarity: I returned this product before using it
  • Fit: True to size

These are a great pant, they are made for colder weather and not casual wear. They are heavier than the LT's and made to last a lifetime. I needed something lighter and will return for the LT's.

I didn't do anything on the weekends this summer except backpack. So when I say these are the best pants ever, I feel qualified.
I've worn these pants in 40MPH winds, temperatures in the teens (F) and snow. They kept me warm, dry and comfortable. They have a little stretch and are cut the same way I am -- no pinching when scrambling & no wedgy when sitting down. There is enough room to layer over expedition-weight base layer but still a nice, clean fit. Despite the use and abuse, they still loook brand new. A nice feature is the 3 pockets are all designed to vent heat if you unzip them.
I highly recommend these pants.

After having more patches than original material on my old soft shell pants, the search began for a replacement. The criteria: Summer Alpine Rock to Winter Alpine Ice. Simple right, one pant for every use?

Being familiar with the Gamma MX Jacket, I knew I wanted a pair of pants that had the same flexibility and durability. In combination with a trim fit, the Gamma AR Pants fit the bill.

These pants are burly, however they are unlined, so layering them with a power-stretch bottom works great for Winter use in all but the most frigid temps. The fabric has held up to bush whacking approaches through dead fall trees and near misses with the points of my crampons. The fabric also strikes a balance between windproof and breathable making them great on the approach through the trees and exposed on the climb.

The fit of these pants is also second to none. The built in belt allows them to be worn next to skin with a quick cinch on warmer Summer Alpine Rock days. They have a trim "athletic" fit that still allows for freedom of movement, with or without layers underneath. So far, soooo good...

Are the cuffs on these pants wide enough to fit around a typical ski/mountaineering boot?

Best Answer Responded on


The cuffs on these pants will fit around a typical mountaineering boot. They can accommodate some lightweight ski touring boots, but the fit is tight...
