More ventilation with a zipper below the pockets.

The pants are almost perfect just ventilation is missing. I put a zipper on the legs between the pockets and the knee. That helps a lot when you hike uphill. In the flat or downhill I close them again.

Always Fail at the glue seams

Expensive pants that fall apart while washing. I own 4 pairs of the gamma pants and anytime I wash them, I fear that the glued seams will fall apart. I wear them to travel, and do not have control over what kind of detergents used in other countries. They are great pants but all the glue seams will fall apart, leaving the thigh pocket useless. Any taped seams will peal. I wish I could attach photos to this review. I will no longer buy these pants again. Do not buy, unless you never plan to wash them.

Durable and dependable

Wore these on a two day 21km hike, loved the durability. Not getting caught on branches etc. also lose how I can pull them down on my boots and they stay tight and won't come off after walking if gaiters aren't your thing. Would definitely recommend

Best I’ve worn in the field

My go-to choice for outdoor adventures. Whether it’s hiking, camping, or working long days in unpredictable weather, these pants deliver on every front. The fabric is tough yet flexible, offering great freedom of movement for climbing, trekking, or kneeling down without any restriction. They’re impressively weather-resistant — light rain just rolls off, and they dry fast when wet. The breathability is excellent too, keeping you comfortable even during high-output activities.

Great pants

Bought these pants for hiking and they have delivered this far. Used them for an overnight backcountry trip and they were very comfortable. I always used to buy Arc’teryx pants one size bigger because they were built for tall skinny people however, by doing so, I had to return the first pair because they were too big and the second pair I bought were actually the same size as I always buy. The material is very comfortable and seems bulletproof. I really enjoy that they are a bit longer and narrow at the bottom so I don’t have to wear gaiters and nothing sneaks inside my boots while on long hikes.

Poor quality - glued leg pocket coming apart.

Really disappointed with these pants. After a dozen or so washes the glued zipped leg pocket is coming apart. Why use glue in the first place instead of stitching? I am now going to have to pay to have these repaired/stitched locally. Another, thing these pants shrink even at a 30 degrees washing cycle and become too tight like skinny jeans. Please bring back the older version which was more comfortable and did not shrink in the was. Over the years, I have noticed that Arcteryx quality has been going downhill. Please focus on good quality outdoor wear instead of the chasing the casual market.

Excellent for Athletic Build - Fully Functional

Excellent! If you are an athletic build ( for example I'm 5'11'', 175 lb, 38-year-old man with a 32-inch waist and 32-inch inseam) these pants are excellent. I usually use them as stand-alone or with a RHO heavyweight baselayer under them in colder conditions and they are phenomenal. They provide enough flexibility while being functional and looking good. I highly recommend. I bought both the Tanto and Black pair. I did however try last years model as they were on sale and had to return them as the 32 inch waist was too tight. This years 32 inch waist fits perfectly.

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...

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).
