Arc'teryx Gamma MX Jacket - Men'sis rated5.0out of5by2.
Rated5out of5byfromPerfect Jacket for high output activitesThis is a fantastic jacket that fits a variety of roles in the outdoor gear quiver. This jacket is designed to be a primary outer layer for high output activities in dry conditions. It breathes extremely well and if you layer well you will be plenty warm in cold weather. I recently wore it with nothing but a thin wool liner while backcountry skiing. The temp was 10 degrees F with moderate winds. The jacket blocked enough of the wind while ventilating my perspiration to keep me comfortable on the ascent. When I came back to the resort and hopped on the lift i threw on a down vest for the lift and I was warm enough on the ride up without overheating on the ski down. Because the jacket is so breathable, it is not going to stand up to heavy winds or heavy precipitation so if you expect to encounter those conditions, you will need to pair it with a shell. The cut of the jacket is something I haven't been able to find anywhere else. I am 6' 3" 155 with long arms and broad shoulders. The large fits like it was made for me with just enough room for a few layers underneath without being so large as to allow drafts of wind in. The wrists fit close so it is easy to keep snow or drafts out. You have two chest pockets and two waist pockets that are all fairly large and easy to access. Great for stashing maps or snacks so you don't have to dig them out of your pack. Bottom line, if you are thinking about buying this jacket, do it, you won't be disappointed.

Rated5out of5byfromGreat Jacket!I bought this jacket in 2010 and had to buy another one for 2013. It has done me well in every setting imaginable: day trips into the wilderness, week-long camping trips, grueling airline travel, sporting events, house parties, and nice dinners. It looks great and does a fantastic job of keeping me warm and dry. The price was well worth the three years of near constant use.
