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.

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.

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.

Wow. Just wow!

I love how lightweight these pants are for summer, plus how comfortable and stylish they are. I also love that they are long enough and have so much trouble finding adventure pants that are long enough. I have a 33 inseam and was thrilled to find these.
