Ever so Slightly larger than previous iteration
At 6’ 205lbs the Large fits perfectly. The previous iteration was too narrow in the shoulders and looked a little off on me. But of course the XL was too big for me. It seems that I’m one of the few people who think the new revisions fit better. I am by no means overweight. I’m muscular and athletic. I’m constantly biking, hiking, and climbing. This jacket is perfect for those things as well as a day to day jacket. I still wish it had the old cuffs from 2017. These glued cuffs with the bunched up elastic aren’t the most comfortable but at least they made them a little wider this time. The 2020 version used to get stuck on my wrists all the time. Overall a good revision.
Definite downgrade
Compared to the previous version this is definitely a step down in materials and fit. Fleece lining is now thinner and overall the material feels much cheaper. The jacket now lacks that premium comfortable feel I loved about my prior Gamma MX. Although Arcteryx claim the fit in the medium is unchanged, after trying on my old version and this one, the revised version is not as fitted through the body, unfortunately. Overall, I'm quite disappointed, as I've owned 5 of the hooded and non-hooded MX jackets over time. All this on top of the fact that it costs 30% more than the previous one. It looks like I'm going to have to start searching for an alternative soft-shell for daily use.
Hello there, thank you for your detailed feedback on the revised Gamma MX jacket. We're sorry to hear that the materials and fit didn't meet your expectations, especially after your positive experiences with previous versions. We understand how frustrating it can be when a trusted product evolves, and we’ll share your insights with our design team.
Well-designed jacket
I love the sleeves are not too long and the cuffs are perfectly designed / contoured so as to not extend over the palm of your hand. The jacket is light but provides decent warmth, which is perfect for autumn / winter in Paris. The fit through the body is roomy and also not too long, which is also good for layering and daily usage.
I love this jacket
I love this jacket. Lightweight but warm. A great fit for a tall guy (6'3" - XL). Color (solitude) is very cool. A number of people have remarked positively upon seeing it. I bought it to wear daily, but also to stick in the bottom of a back pack when hiking in the shoulder seasons or at altitude
Needs pit zips!!!
This jacket used to be awesome! I had one for years - great protection from wind and cold when climbing on my tele's and then threw a hard-shell over it for the downhills. I finally need to replace it but the new model no longer has pit-zips which are a must-have for the climbing :-(
Hi there. Thanks for sharing your feedback on the Gamma MX Jacket. We are happy to hear how satisfied you have been with your previous one. We do, however, understand how the new version not featuring pit zippers can make a difference. We will make sure to pass your comments to our team.
EXPENCIVE TRACK TOP
Compared to the previous version this is definitely a step down in materials. Very soft and comfortable inside, but not feel like shell jacket. Pockets fine. Slimmer than Gamma MX hoody. As very many other customers I'm worrying about the materials all over with Arcteryx.
Hello Kari, thank you for sharing your thoughts on the Gamma MX Jacket. We appreciate your feedback on the materials and fit. While this version maintains the balance of warmth, stretch, and breathability the Gamma series is known for, we understand that changes in design can feel different from previous iterations. Your input is valuable, and we’ll be sure to pass it along to our team.
Sadly - no longer available with pit zips!!!
Such a shame that you can no longer get this jacket with pit zips. If you are the type of person who charges hard uphill, you need protection from wind and moisture while being able to let off steam!
Hi there. Thanks for sharing your feedback on the Gamma MX Jacket. We are sorry to hear that you are disappointed with it not featuring pit zippers. We will pass your comments to our team.
Good look but...
Nice design and look to the jacket. The sleeves however are too tight and the insulated lining does not move smoothly over any undergarment
Hi Ian. Thanks for sharing your feedback on the Gamma MX Jacket. We are sorry to hear that the sleeves were tight and that it did not suit your needs. We will pass your comments to our team.
