Awesome as an all around jacket
I bought this to replace my 6 year old Gamma AR that has been to hell and back. I was hesitant to buy this because I really like the stretchiness of my Gamma (made of the old polartec material) and this jacket has almost no stretch to it. But I found it on sale in black for under $200 locally and it fit me pretty well so I bought it anyway.
I'm 5'7" and float between 174-182 (muscular/athletic) with broad shoulders and this jacket in a medium fits me very closely with a T-shirt, polo, or other thin layer under it, which is what I was going for. I used to layer my Gamma (size L) over a hoody for cold days, but this jacket is to trim for that. The fit and style is clean and sharp, which is great for wearing around town.
It's thin and light, but deceptively warm but breathable. I've used it for running hills in 28-30degree weather, warming up for tennis in 50degree weather, and I even wore it watching a baseball game in sunny, 70 degree weather last weekend. I could probably use it for drier days on the ski slopes, but I have other jackets for that so I probably won't.
This is my 5th Arcteryx jacket (and my 2nd China-made one), and the construction is second to none, as always. Just like everyone else, I was disappointed when they moved their manufacturing to China, but I have seen no evidence that quality has suffered as a result and I wouldn't hesitate to buy another China-made Arcteryx jacket.
