Guy B. wrote a review of Arc'teryx Beta AR Jacket - Men's on January 10, 2013
Familiarity: I've used it several times
I own about 9 Arc'teryx pieces and they all vary greatly in fit. This jacket is bomb-proof and will probably weather anything nature can throw at you. I returned it due the fact that it fits Huge. I always buy XL (6-6, 210 lbs) so I can layer. But this jacket has so much extra room that I felt lost in it. It also is kind of overkill for 95% of the time I need a shell. I wore it on Rainier and Mt Washington but I could have gotten by with a lighter shell. I ended up getting an Alpha LT for Winter and an Alpha FL for Summer.
