Loved the feel of the material and the Windstopper fabric, but the sleeves are just too tight. I am 6'-4" 220 lbs. and bought the XL. the length and body fit were perfect. I have standard size arms (not built like Popeye), but the sleeves are skin-tight. No way to ever think about a base layer underneath, and the first time I took it off I noticed the arm stitching was coming undone. Unfortunately a major design flaw.
