Chocodovewrote a review of Arc'teryx Alpha SV Jacket - Men's on January 25, 2016
Familiarity: I've put it through the wringer
Fit: True to size
Yes, it's expensive. But I do believe you'll never have to buy a hardshell again. I use it primarily for hiking and mountaineering in the northeast. Lame winter so far, but I had it up on Katahdin in classic whiteout blizzard conditions earlier this month and it was very nice to have this between me and whatever Mother Nature decided to throw at us. Complete piece of mind. It fits great, is constructed like a work of art, and is the very definition of the word "bomber". I've had every fabric and trend to come out the past several years, and if I had to choose one shell to get me through anything, this is it. Not the lightest or most breathable, but if you want fool proof protection, this is it. My friend had on a lightweight neo shell piece for this trip and it got shredded. He's currently attempting to send it back to the manufacturer. No comparison.
I have an Alpha FL as well, but I much prefer the fit on the SV for winter layering.
PS: The Adriatic Blue color is awesome and MUCH darker in real life than in the stock photo. See my pic.
