The highly wind and water resistant Polartec Power Shield fabric on this breathable Arc'teryx Gamma MX Jacket makes it a great choice for moderate weather protection for strenuous outdoor activities. Climbing Magazine gave the jacket their Editor's Choice award for alpinist versatility. It's made with Polartec Power Shield fabric, a technical blended material that features tightly woven nylon on the outside laminated to a wicking insulation layer inside, so it protects you from the elements while still allowing for breathable soft shell performance. If you ski or do any type of climbing, the Arc'teryx Gamma MX Jacket has you comfortably covered in mild weather or broken cloud conditions with short bursts of rain or snow. Stitch-free laminated zippers, pockets and drawcord optimize the technical protection while reducing the overall weight. Added touches like a soft brushed collar lining and streamlined interior wind flap enhance the comfort options better than some minimalist-configured soft shells. If you're looking for a similar configuration with a helmet-compatible Storm Hood, take a moment to check out the Arc'teryx Gamma MX Hoody.

Customer Reviews for the Men's Gamma MX Jacket
Warm, light, and versatile.
I like this light weight jacket, which is perfect for layering. I wear it in the city, in the ski lodge, in the parties... Size Large is perfect for 6 feet, 180 lbs. neck size 16 and sleeves 35! I got long arms and it is perfect!
high quality
from it's light weightiness to it's attention to detail (zipper action, etc.), very nice jacket. I also like that it does not have both the arcteryx symbol and arcteryx also spelled out (i.e., some of their other softshells), which is a bit overkill. But don't buy it unless you are in love with the style and it fits you great, too much $$. Remember, it is a splurge.
Best Soft Shell on the Market
I just got this jacket after trying on all of the Arc'Teryx Soft Shells, and I can definitely say that the Gamma MX is my favorite by far. While it is not Gore windstopper material, it is much warmer than the windstopper soft shells and blocks about 90% of the wind. Which from living in San Francisco, Seattle, and LA is perfect. In fact I would say that if you live in either of those three areas this is the perfect jacket. I wear it walking the dog at night, traveling, and pretty much everywhere I go. I combine it with my Marmot Oracle jacket as a rain shell and I feel good to go. The fit is much more stream-lined than the other Arc'Teryx soft shells (which I like), and the wrists actually are fitted (which I also like). I'm 5'10", 195lbs, with broad shoulders and a large fits me pretty well.
