tismondowrote a review of Arc'teryx Beta AR Jacket - Men's on December 1, 2004
After about a month using the Arc'teryx Beta AR jacket, I must say I'm quite impressed. The waterproofing is incredible (expect nothing less from GoreTex XCR) and the fit is absolutely perfect. I've taken this guy biking several times in the cold rain and havent been let down yet.
Note that this is a shell ONLY (no insulation), is a short cut (by no means close to a parka) and is made to be lightweight. Some might find the pricetag high for what it does, but keep in mind that this jacket does what it does EXTREMELY well, and that the pit zips are a huge bonus (they seem hard to find in jackets of this type these days...)
I've only had this jacket for a month, and have not yet put it through the numbers... but for what I've asked of it, it has delivered.
Bottom line: Only buy this if you're gonna use every penny you pay for it.
