My favorite pants for this autumn

[Employee of arcteryx] I’ve owned this pants for a few months now, and I’m still loving them! They're warm, cozy, and perfect for hiking. The fabric is soft to skin and provides great insulation, keeping me comfortable on cooler days. They allow for easy movement and have deep pockets for my essentials. Plus, the fit is stylish enough for everyday wear. Highly recommend these for anyone who loves the outdoors!

The best pants for hiking/cold weather climbing

LOVE THESE PANTS! The pockets are huge and can fit a lot. I think the fit is better than the original Gammas, but I still need to size up one size to be able to fit them properly. They end up being baggy towards the bottom, but I can deal with it for a decent pair of pants. I also don't need to add a base layer on warmer winter days which is great!

Great features!

Two years ago I bought the lighter version of this pant in a 10. I have two new grandchildren, am back in New York, and gardening a lot outside. Loved the pockets, toughness, and attractive fit and versatility. Now bought this heavy weight version to be warmer walking and hiking and took the 12 to account for pounds gained during pneumonia. There is plenty of room for a base layer and the doublesnap waist closure works fine and has a good adjustment feature so should be good as I move more. For hourglass figure a very attractive fit and designed so well for sitting on the ground. Sturdy in 40 mile wind and dried right away when my grandson poured liquid on it in fabric experimentation. Love them.

Please bring back belt latch and slimmer cut :(

Dear Arcteryx, Gamma MX has been my favorite pant for over a decade, I made sure I bought one in every color each time when you had it in short size like mine. I waited patiently over the years as product teams listened to customer feedback. I agree the newest edition has been disappointing in two folds 1) the secure latch is missing, only a button now. This makes it easy to come off during climbs. I noticed the men version still have the metal latch. Can we please bring them back and make them at par for women too? 2) baggy. It doesn't look as stylish anymore. If the intent is to serve broader, more universal wear then you may lose your athletic build customer base :( Please do not lose your niche market. It feels more like mainstream brand these days :(

Hello there, thank you for taking the time to share your long history with the Gamma MX Pant, hearing from guests who have relied on this piece for over a decade is incredibly meaningful to us. We’re sorry to hear the latest version hasn’t met the expectations set by your previous pairs. The shift from a metal hook to a button closure and the updated, more relaxed fit are part of a broader redesign intended to improve comfort, layering compatibility, and versatility across a wider range of activities. That said, we understand how important a secure closure and a more athletic silhouette can be for technical movement, and your feedback is being shared with our product teams as they continue to evaluate these updates. We truly appreciate your loyalty to the Gamma line and the care you’ve put into voicing your experience.

Lacking air vents, otherwise perfect

I really love the product — it’s exactly what I was looking for — but the price tag highlights the most important feature it’s missing: air vents. For such warm pants, that’s an essential feature for the approach. In the end, I didn’t buy them because they aren’t versatile enough for the price point, which is sad. I really think there are no pants for women designed specifically for winter scrambling, ice climbing, and winter multipitches. This was my closest shot, but the money can be better invested in something cheaper.

Hello Ardita, thank you so much for sharing your thoughtful feedback on the Gamma MX Pant. We’re glad to hear the product aligned with what you were looking for in many ways, but we understand how the lack of air vents can be a dealbreaker, especially for high-output winter pursuits. Your insight about the need for more versatile women’s pants designed specifically for winter scrambling, ice climbing, and multipitch objectives is incredibly valuable, and we’ve shared it with our design team. We truly appreciate you taking the time to highlight this gap, it helps us evolve our offerings to better support your adventures.

Baggy in all the wrong places

Baggy in all the wrong places. It was agitating to have so much material flapping around my fee.t, kind of like baggy dress pants and high heels. I am 5'3, 150 lbs, I ordered a size 10 due to my previous 8s (maybe the SL version) being a little snug and missing the hook and loop snap. The snap felt itchy against my skin and the rest of the material was also itchy. The short size has always been perfect, but unless I yank these into highrise mode, the short was too long.

Updated fit even better

Second pair of these pants. The updated fit is flattering, slightly less baggy bum and flatter waistband cinch that is easier to adjust. The material is so robust, dirt brushes off and they wash really well, no shrinkage. Love the soft, fleecy inside although I usually wear long underwear underneath. Use for everything, snowshoeing, hiking, town, even eating out coz they fit so nicely. I'm 5' 4", athletic build and bought size 6 reg.

Very large, baggy rear, hip and thigh.

Lining is perfect for hiking in 40 - 50 degrees farenheit weather and plenty of room to wear long underwear for colder days. Four large zip pockets with lots of room for keys, ID, etc. Only negative is the very large and baggy rear, hip and thigh. I am 5 ft 10" tall, 141 lbs. Athletic build. Bought a size 10. I kept them because they are perfect for cool and cold weather hiking, but they are not flattering.

Revised Gamma MX pant is no good

Arcteryx has changed the fit of this amazing pant. I am so disappointed. They revised the leg to be wider and fuller and there’s too much material. Even in a size 0 or 00 there is too much room in the leg. Besides the new cut of the pant, these are amazing pants. But they do not fit like they used to and I would not recommend.

Hello there, thank you for taking the time to share your feedback on the Gamma MX Pant. We’re sorry to hear that the revised fit no longer works for you, especially since this piece has been a favorite in the past. Your comments about the fuller leg and increased volume, even in the smallest sizes, are important for us to hear, and we understand how a change in cut can significantly affect how a pant feels and performs. While we’re glad the overall quality and design still resonate with you, we’ve shared your input with our product team as part of our ongoing effort to refine and improve our fits. We truly appreciate your honesty and your support.

Waist button clasp needs to go!

The button clasp to close the pants on the waist is the worst. I've had this issue with all Gamma pants with a button. Where it lies on my stomach causes pain in both a size 0 (my usual size) and the size 2 (too big for me regardless). I wish these had no button, just stretch/elastic waist for comfortable tummy expansion.

Hi there, thank you for sharing your experience with the Gamma MX Pants. We’re sorry to hear that the button clasp causes discomfort. That is understandably frustrating, especially when you expect a secure and comfortable fit. Your feedback is very valuable, and we have passed it along to our design team as we continue to refine our products. Thank you for taking the time to leave a review.
