Product Description Item No.   10281204

The Arc'Teryx Men's Gamma AR Pant is a softshell pant for technical climbing pursuits on rock, alpine and ice, as well as cool weather hiking. When the temperatures begin to drop and you need to perform well in the mountains, grab these abrasion-resistant pants, constructed of a nylon, polyester and elastane blend. The smooth exterior is tough against a rocky terrain and wind resistant yet breathable so you can work hard without overheating. Brushed on the interior for a soft feel against the skin, plus a chamois lined waist for comfort under the harness and/or pack. The trim fit won't get in the way of other gear or caught on wayward branches while three zippered pockets secure your candy wrappers until you make it back to the trash can at the trailhead.

FEATURES of the Arcteryx Men's Gamma AR Pant

  • Burly Double Weave is a durable moisture and wind resistant fabric with 4-way stretch; outer face has DWR finish

  • Gusseted crotch and articulated patterning for full range of motion

DWR tech

Durable Water Repellant
DWR (Durable Water Repellent) is a coating that is applied to fabrics which makes them water-resistant, or hydrophobic. A DWR finish doesn't interfere with breathability, which makes it perfect for adverse conditions in the backcountry.

Rated 5 out of 5 by from Great All Around Pant! These pants do everything the Arc'teryx description claims. These are my 3 season hiker. I've use these on 60* days and haven't felt like I was overheating. The morning dew beads up and rolls off and they do block the wind well. I think they would work in every condition but the warmest of days and torrential rain. My only complaint for these and my Gamma LT's is that personally I wish the leg openings were about an inch, maybe two larger so they would fit over my boots a little more casually. But this is just preferrence as if it were the case I would wear them everywhere.

Rated 3 out of 5 by from ! week in the Cascade Mountain Range humbles these soft-shell pants First off, I am a "deadbird" gear fan. I have 7 different jackets, 7 pair of pants and shorts, and many accessories. I was so stoked for these pants and to use on Mt. Baker for a week long of alpine training. The likes: * Short length sizes (i have a 30" inseam) * warmth * water resistant * look good The dislikes: * not too durable I have a hole all the way through from the outside to the inside from a week of simply sitting on rocks. I would thing they would be more durable and abrasion resistant. I did not misuse or abuse the pant. This was simple from sitting on the rocks for an evening meal and putting on boots in the morning. so it doesn't look like this will last long if this is going to be common with normal everyday use. A little disappointed. T.

Rated 5 out of 5 by from The fit of these trousers is perfect for XS men like me Bought for general hiking but First worn in a dog agility final at Crufts 2015 because they look so good. Superb four way stretch suited this activity well. Can't wait to try them on the hill and for scrambling. Very comfortable.

Rated 5 out of 5 by from Arcteryx: More than raingear! Few hiking pants are both tough and comfortable. Gamma ARs are the exception. Lightweight pants don't protect one's legs off trail: in bushes or talus. I sought out pants made of material like Fortius 1.0, used for tough shells. Only Arcteryx makes such pants. Gamma ARs are as comfortable as lighweight pants, but they protect like chain mail. For instance, their burly weave material breathes. It takes a good downpour for water to soak through (They dry quickly).

Rated 4 out of 5 by from Fuctional, but tight Purchased a medium, tight fitting. (Buy one size up/ strongly recommend trying one in store). High outlining crotch, overall close fitting, pocket punctured after carrying torch inside for a few days. Otherwise, looks good, good temperature regulation, good design

Rated 5 out of 5 by from the perfect alrounder i bought these trousers from up & under in cardiff (uk) ... wow, i have several pairs of assorted arcteryx trousers but these really are something else. The cut and sizing are spot on for me being 5' 8" medium is perfect. The quality of manufacturer was as expected for arcteryx but the fit feels like a tailor made pair of pants. Not the usual baggy outdoor type that others do but just fitted enough with restricting movement. The stretch feels so good and they dont ride up whilst climbing or kneeling. I wore them during a wet miserable day in the uk ( normal for us) and the water just beaded off without anything getting through. not a downpour i admit but enough to wet out lesser pants) My beta ar pants stayed in my sack ! All in all i can heartily recommend these pants for at least 3 seasons and for 4 if you layer up underneath. Well done arcteryx you prove once again that perfection costs but its well worth it . Keep up the good work, Mark Hopkins (Cardiff Wales UK)

Rated 5 out of 5 by from Ouch - they're nice. The pant fits as well as True Fit promised, ie 'True To You' with a 4.5 on the fit graphic. As per the Gamma AR pant, my optimum inseam length is somewhat between the Large and Large-Tall--I went with Large-Tall. Some Arcteryx pants fit perfectly in size Large (Nalix) and some fit best in size in LT (Beta AR). The Gamma AR in Large is ever so slightly too short and the Large-Tall is about 1 cm 'too' long (the cufff folds somewhat under my heel when but in socks). Anyway, better the extra length for 3-season use and bulkier/taller footwear. Apart from sizing, I went with black even though my first pick was Anvil Grey (Anvil Grey LT wasn't available when ordering from Arc'teryx's site and the retailer where I tried on the Anvil Grey in LT forgot to hold them for me during the 6 hours it took me from trying them on to making a round trip home to pick up my AmEx to close the deal.) The pant holds true to their listed spec sheet. They look very sharp, draping in a manner almost too flattering to be outdoor pants. Last weekend, I wore them over Icebreaker 250-weight leggings on deck on a crossing of the Baltic Sea during a storm with 50 km/h winds gusting up to 100 km/h (ca. -5C). I was comfortable with no nagging chill over my legs. (On top I wore a Smartwool Midweight (250) LS top, Arc'teryx's Rho AR Zip Neck, Patagonia's Nano Air, and a Squamish Hoody...topped off with a windproof hat--I was golden during my 2-hour stint on deck. Given, the deck was ca. 10 meters above the churning sea so splashing waves wasn't an issue. The DWR on the pant and Squamish dealt effectively with the spray that made it to deck. I also wore the pants on a 2-day, 50-click hike with a backpack weighing in at ca. 12kg. The pant with its cut and stretch were comfortable and the built-in belt didn't impinge on my comfort whatsoever when worn in conjunction with my backpack's tightly cinched hip belt. The pant's DWR was as satisfactory as that on most of my other hiking/action pants (mostly Rab). I've yet to wash the pant so I can't attest yet to how the DWR holds up after several such cycles. I haven't skied in the pants but I plan on doing so soon and the LT's extra length will come in handy then. I can't imagine that the pant won't be plenty tough to handle resort based skiing--but we'll just have to wait and see. So bearing in mind the limitations of the gauntlet that I've subjected the Gamma AR pant to over the past fortnight, I'm going with a five star rating of said pant--imho, they're functional, tough, sharply tailored, have solid (irl) technical specs, all at a relatively nice price...and they're comfortable on their own or worn over 250-weight merino leggings. In fact I like them so much that I'm going to try to scrounge together the cash to get a pair in Anvil Grey. The only other item in my outdoor wardrobe of technical pieces that I'm planning on redundantly doubling down on is Arc'teryx's Squamish - but that's a rant for another day.

Rated 5 out of 5 by from Good Pant Originally purchased these for backcountry skiing, soon enough they became my go to pant for all my hiking activities where it might get a little cool or wet. Sheds water, good breathability, and very durable. This will be my second year with this pant and I look forward to using them more.

How waterproof are these pants?

Asked by: Maz15
Thanks for the question! The Gamma AR Pants are actually Water-Resistant with a DWR coating, not Waterproof. I see we have the incorrect information on the product page. I will get that corrected right away. Hope this helps!

• Please note that all the info provided above refers to body measurements, and NOT the dimensions of the garment.


Next to Skin Fit - These snugly-fitting garments are made with stretch fabrics to fit next to the skin to enhance moisture management and thermal efficiency. Garments in this fit category when constructed using Arc'teryx's heavier-weight AR and SV fabrics also perform very well as mid layer pieces, and users should consider selecting a larger size to accommodate a base layer underneath if the intention is to use this layering system as a mid layer option.

Trim Fit - Trim-fitted garments share the motion-friendly traits with Arc'teryx "Athletic" fit garments, but are patterned with lower volume for reduced bulk. These close-fitting pieces layer well under other garments.

Athletic Fit - This is the "Arc'teryx Standard" fit. These complete patterns utilize anatomical shaping and gussets to enhance motion by minimizing excess bulk. Easy layering under or over each item extends seasonal versatility and comfort.

Relaxed Fit - Relaxed fit garments rely on higher volume patterns and a reduced amount of articulation to offer roomy mobility.

Expedition Fit - Cut roomier than the Arc'teryx Athletic fit and suitable for winter/extreme conditions, Expedition (XPD) fit garments are cut larger to accommodate multiple layers without binding or restricting movement.

• You can find the fit type and additional fit info for Arc'teryx styles in the product description FEATURES and SPECIFICATIONS.
