Old version was better

I usually like the changes made to new versions, but I am quite disappointed in these. I bought them to replace my 2019 Gamma AR pants, which I used as my main winter pants. I can't imagine using the new version for the same purpose. The material is way thinner. And the fit is much slimmer, not great for layering underneath or fitting them over big boots. I have the regular Gamma pants in the same size and they fit way better. Not really sure what the use case is here with the new ARs. Maybe the MX is the new winter pant?

Hi Kyle, thank you for taking the time to share your feedback. We're sorry the updated Gamma AR Pant didn’t meet your expectations, especially as a replacement for your 2019 pair. Some of our gear does undergo revisions over time, and we understand that changes in fabric and fit can impact how the item performs. The 2025 Gamma AR Pant uses a lighter recycled nylon double weave and plain weave construction, which differs from past versions’ heavier 4-way stretch double weave with brushed tricot and microsuede. This update improves mobility and breathability but may feel less substantial in colder conditions. The trim fit is refined for climbing and mixed terrain, so if layering is important, sizing up might help. If you're looking for something closer in warmth and feel to your previous ARs, the Gamma MX Pant could be a great alternative. It features a regular fit and is constructed with a synthetic stretch softshell backed with polyester fleece, offering a superior warmth-to-weight ratio and greater insulation than the current AR. We’d be happy to help you explore options that better suit your needs. Please don’t hesitate to reach out. We’d love to help you find the right pants. https://arcteryx.com/ca/en/help/contact

Too slim fit

1.Fit is unfortunately a Lot more slim fit. 2.Fabric is Different than the older version. I have the 2023 versiĂłn and this current new fabric is Slightly thinner and feels not so embodied. I bought 2 units to feed my needs for a long time because i wanted them for my 1st option and, sadly, when i tried, they were so slim that i had to return them. A real pity

Hello Tony, thank you for taking the time to share your feedback on the Gamma AR Pant. We’re sorry the updated fit and fabric didn’t meet your expectations. This style has undergone sizing revisions and material updates to enhance performance and mobility, particularly for technical movement and climbing. These changes have resulted in a more fitted silhouette, which may explain the slimmer feel you experienced. We know how important consistency is when you’ve found a go-to piece, and we’re sorry this update didn’t deliver that for you. We’d love the opportunity to help you find a style that better suits your needs. If you’d like further assistance, please don’t hesitate to reach out, our team would be happy to help. https://arcteryx.com/ca/en/help/contact

The definitive pants, at last!

This is the best pair of trousers Arc'teryx has produced to date; they are more versatile, feature a slimmer fit, and are supremely comfortable. And that’s coming from someone who owns five different models.

Very comfortable

I have worn these a couple times since I bought them. Very comfortable. Looking at getting a second pair. Fir as described.
