Miss the old Gamma LT

I miss the old gamma pant design which had a buckle clasp which covered the button. The new design has a tendency to pop open when I climb. The fabirc is good, pants look great, but the redesign has been a dealbreaker and I now need to find a new brand of softshell pants to replace my aging fleet of Gamma LT pants

Hi there. Thanks for sharing your thoughts on the Gamma SL Pant. We understand how the change in the waistband design can impact performance, especially during active use like climbing. If you’re looking for a closer alternative to the previous Gamma LT, we’d recommend checking out the Gamma Pant, which offers a more robust build and a design that may better suit your needs. We have, however, passed your comments to our team.

Nice pant with big flaws

I like the pants overall, the material is breathable and I find them comfy in muggy or wet conditions. They're also not too noisy as you walk. The big problem is that they're advertised as being comfortable under a hip belt of a pack. The zippers of the pockets are located in such a position where they dig into your skin under a hip belt (the zippers were pressing into my hip bone which was extra uncomfortable). If you're a backpacker I would look for other pants as the zippers will start bugging you after a couple hours. I keep the pockets unzipped to solve the issue, but it's still a questionable design choice. The button could also be improved as it can pop open like other reviewers have said.

Hi there. Thank you for your feedback on the Gamma SL Pant—we’re glad to hear you’ve found them breathable, comfortable in damp conditions, and quiet while moving, and we appreciate you pointing out the challenges with pocket zippers under a hip belt and the button closure. We understand how important comfort is for long days on the trail, and your experience will be shared with our product team as we continue to refine design and fit.

Not very flattering fit in the front

The pants are comfortable and well-made, but the fit in front is unflattering. The crotch area pulls and bunches awkwardly, creating strange creases across the front. Additionally, the color is quite different from the photos - it is just a plain dark blue.

Hello Dasha, thank you for your feedback. We're glad to hear you find the Gamma SL pant comfortable and well made. We're sorry the fit wasn't what you expected. Regarding the fit, the fly is designed to sit comfortably without excessive pulling, and for a better fit, you may wish to explore a larger size. Regarding the colour, please keep in mind that colours can appear differently depending on your screen settings, so the actual shade may vary from what is shown online. If the fit isn't right for you, please note that items purchased through Arc'teryx can be returned within 30 days of purchase, provided they are in like-new condition with the tags attached. Thank you again for your comments, and we'll be sure to share them with our team.

Some good, some not so good

These are an excellent weight but the design/durability could be improved. Wish the leg was less tapered or had some stretch at the bottom to roll up (very tight), and wish the fabric was more durable. Worn one day rock climbing and have multiple holes

Hello there, thank you for sharing your experience with the Gamma SL Pant. We’re glad to hear the weight worked well for you, and we’re sorry to learn that the lower‑leg taper and fabric durability didn’t meet your expectations, especially during climbing. The Gamma SL is designed as our lightest softshell option, built for fast‑moving missions where breathability and packability take priority, which means the fabric is intentionally more minimal than the Gamma or other climbing‑focused models. That said, your feedback on the leg opening and your experience with abrasion on rock is incredibly valuable, and it will be shared with our design teams as we continue refining the balance between mobility, durability, and weight. We appreciate you taking the time to help us improve the line.

Great, super-light material for hot days of hiking

Lightweight fabric is great for hot days of hiking and has stretch and breathability!! A few quibbles on the design. The fit is slim, so the zipped pocket by the thigh is not useful for cell phone or anything beyond a tissue, especially if you have muscular thighs. Articulation at the knees enables the slim fit, but if you're petite or have short legs, the articulation doesn't match up to the knees (BTW. 10S sizes in most Arcteryx women's pants always seem to be sold out). A regular fit in this great fabric would be so much better, IMHO.

Bring the old style back please

The pants are breathable & the stretch and articulation makes them nonbinding and comfortable. The problems are: the ankles are so tight I can't pull them over my skinny calf for stream crossings - leaving me hiking in wet pants! The old style didn't have this problem. The button is hard to snap close and pops open. The zipper hip pockets hurt under a pack belt and are unusable. The thigh pocket is great for holding your map for easy access. It would be great to have a pocket on each thigh.

Hi Rhonda, thank you for taking the time to share your feedback. We're happy to hear you're enjoying the breathability, stretch, and comfort of the Gamma SL Pant, and that the thigh pocket has been a useful feature for your map on the trail. We also understand your disappointment with some of the design updates. Hiking in wet pants after a stream crossing is no fun, and when you've found a piece of gear that works just right, changes to a favourite product can be especially noticeable. We know finding the right fit and functionality can be challenging, and feedback from long-time users like you is incredibly valuable. We appreciate you sharing your thoughts on the ankle openings, waistband snap, pocket placement, and the idea of adding a second thigh pocket. We'll be sure to pass your comments along to our design team. Thank you for helping us continue to evolve and improve our products for future adventures.

Favorite summer hiking pants!

These pants are very well made and styled, comfortable with just enough stretch but not so much that they become baggy. I was them in cold water on gentle cycle and allow them to air dry. After many washes, they look like new. I am 5’ 71/2”, 125 lbs, 28” waist and 34” hips. I purchased 2 pairs in size 4 and they are quite fitted in the waist, but very comfortable and appear like a made to order fit. I wanted the option of a bit more flexibility in the waist so I ordered another pair in size 6. I appreciate the extra waist allowance, but the fit appears a bit loose with extra space especially through the hips. The little tab that allows for slight adjustment in waist fit is much appreciated…I will enjoy all three pairs. The difference in size isn’t tremendous and allows for one to select a trim fit, or opt for a bit more flexibility.

Love these pants!

Just wore these while hiking the Tour du Mont Blanc and they were awesome! Lots of stretch to them, and they held off a light rain really well. They were so comfortable, I didn't even notice I was wearing them at all! The adjustable waistband is great and the longer length kept the dirt out of my boots. Lots of pockets with zippers to keep items handy but safe. My new favorite hiking pants!!

Great light hiking pants for Spring and Summer

I recently picked up a pair of the Gamma SL pant, I had eyed these for a while and quite liked the slim fit look. I already own the tapered (love the tapered look) which I have worn through all the seasons and decided to get these in Black to bring into my collection. I really like them! They're slim fit, incredibly comfortable (forgot your wearing pants type of comfort) and soft. I got a size 6R (reference I am 5ft7 and usually go between a 4 and 6), the 6 fit perfectly, I don't think I would fit in a 4 tbh so for those on the fence I might suggest sizing up. Wore them hiking, no noticeable movement sound from the fabric material, haven't used the pockets (the slimmer fit means I'd probably just keep spare tissues). They held up well to dog claws and even a bite from a overexcited pup so durability wise I have no concerns. These will definitely be in my spring and Summer hike rotation, but with slimmer fit I'd probably not wear in colder months due to layering thermals which i think would be too restrictive.

My second pair!

I bought these pants in orange a few years back. They are great for cool days on the golf course. Nice stretch, easy to swing and walk the course. I like the little adjustment on the waist. Time is making me a little rounder in the middle, so this is a great feature.
