Chris W.wrote a review of Arc'teryx Sidewinder AR Jacket - Men's on March 2, 2010
After recieving this jacket, I determined that the collar was a little too big for my liking. The way the zipper comes sidewinding up the neck for me was a con. Sometimes I like to have the zipper unzipped a little ways; with this jacket doing so is awkward and looks foolish. I ended up exchanging for a Theta AR and will see how I like that as soon as I get it. Easy returning items with Backcountry and Arc'Teryx is certainly top quality. If in between sizes, go with the smaller one as they are a little roomy for layering.
