First and foremost Campsaver is the bomb! I recently purchased the Alpha AR and I must say it is slightly large even for a guy with a weight lifter chest. I'm 5'9 and 190 lbs and usually large fits me perfect. The AR large is more like an extra large. I dare not go medium though as it would be too tight in the arm pits/arms. If you have smaller arms and chest you'd be best suited with medium. The AR does fit perfect with 2 layers underneath though. Apart from sizing, this jacket has every function I need, is well made and nice on the eyes. Definitely recommend it.. -JR-
