Just arrived today and the waist is not the size it says it is. The tag says 32”. That’s what I ordered. I measured the waist though and it is 42”. Obviously way too big, and now I have to pay for return shipping which is silly. I was hoping to use the pants this week and now I can’t. Very bummed.

I now own 6 pairs of this Gamma pants, recently bought the Void & Dk Stratus, all size 30 and all fits perfectly well. Also own the Relic, Chloris & Relic colors. I used these pants for my hiking trips, recently in Patagonia for 100 miles. Quality is superb, walked through bushes and no scratches. Protects well again wind & rain as well. Love how much lighter these pants are, less weight on my back (backpack). The breathability & anti-stink technology is great for multiple days of wear.

Great but...

5 months ago

Great pants but wish for some changes for the next version. I would love if there were zippers down the sides of the legs (starting from right blow where a harness leg loop would be and end a little below the knee) for venting. And these are 'climbing' pants but when wearing a harness in them it feels like my crotch area is getting smashed. I have other pants that are not climbing specific pants, and they are way more comfortable and relaxed in the crotch area. So, I would love some new design around the crotch being roomier and more comfortable while in a harness (especially when sitting in the harness).

Great Pants

8 months ago

I really like these pants. Fit is great for me. Durable and somewhat weather resistant. I like that there is no pocket on the back. You would only be sitting on what is in there. Only down side is the fly zipper is too short. Arc'teryx has done this on a number of there pants. I really can't figure out why they can't get this right. It's not that hard. Shorter than any zipper on any pants I have. Levis, Patagonia, Duluth trading company, etc etc. It makes it really hard to have a pee with a harness on or even without a harness you have to undo the waist so you can drop the pants a bit.

Best cold weather trousers

7 months ago

Great outdoor trousers. The fit is slightly tighter on the lower legs than the gamma (non-mx, former light) trousers but the upper part is roomy enough for good mobility, they fit well muscular legs. Great material, solid weather protection while still warm and breathable. Great pockets. The lace hook can be tucked in a fold when not needed, nice touch. The design of the new belt loop and press button is much better, the belt is now very unlikely to open by itself (an issue with the non MX gammas). As a great bonus, they do look pretty sleek and not unsightly at all if worn in town.

Great pants. But?

8 months ago

I really like these pants. Durable and somewhat weather resistant. Fit is great for me and it's great that they come in several different colors and inseam sizes that are actually available. Slim fitting but enough room to move if you have outdoor athlete thighs. I like that there is no pocket on the back. You would only be sitting on what is in there. Only down side is the fly zipper is too short. Arc'teryx has done this on a number of their pants. I really can't figure out why they can't get this right. It's not that hard. Shorter than any zipper on any pants I have by many different outdoor and jean companies. It makes it really hard to relieve oneself with a harness on. Even without a harness you have to undo the waist so you can drop the pants a bit.

Very comfy, maybe noisy

8 months ago

I love how they fit and feel. BUT.... they seem to make noise when I am walking. No one else has this complaint, so I am wondering am I being too critical? I have a few different Arc'teryx items, and they all work great. On the high end of the budget, but I do some serious solo backpacking and rather have quality over savings.

Overpriced....and worth it!

Overpriced, but worth every penny. These pants were a lifesaver while trekking trails and streets in Germany and Austria. Extremely well made and comfortable.
