I've had this for over a year now, and its still going strong. Good for layering - not that warm by itself. The magnetic chest pockets are the single most awesome thing I've ever had on a piece of clothing before. I'm 5' 11" and 180lbs. The Medium fits perfectly. If I was going to be wearing hoodies underneath a large would be better, but I usually wear it with a t-shirt or by itself. This is a good buy especially if you can snag it on Whiskeymillitia.
