Brian Z.wrote a review of Arc'teryx Beta AR Jacket - Men's on March 31, 2019
Familiarity: I've put it through the wringer
Fit: Runs large
This is now my standard use hardshell for all activities requiring the use of a rain jacket and/or hardshell.
I have a hardshell quiver of 3 jackets, and while no, I don't have a single jacket that could be called "ultralight," my next lightest jacket is 5oz lighter, and believe me, it isn't worth using it anymore. The incredibly weight conscious would disagree with me, but I find the weight savings negligible for the amount of bomb proof protection I get.
Stuffing it into it's hood is as packable as it gets and for those of us that are profuse sweaters, I don't think there is a single hardshell on the market that will help us all day long. That being said, I appreciate a jacket for pit zips, and I'm more than happy with the weight penalty for their inclusion.
Fit is a little bit baggier than I expected, especially on the arms. I did size up for winter activities as well, but if you're solely concerned with warmer activities you can probably size down.
My only real con is a pro and a con. The seperated collar design, while fantastic in most conditions, is less than ideal if you have a layer with a hood. In order for your layers hood to not be formed to the back of your head (due to the stiff collar), it has to be stuffed down below the collar, or used.
Overall, in my opinion, there isn't a jacket on the market that fits the "all around" bill better than this one. Highly recommend.
