I'm 5'9 135lbs and the size small couldn't fit better. The material of the jacket is very comfortable like a medium thick sweatshirt fabric . The style is flattering and could be worn to something less casual. I like how the collar can be worn buttoned up and the lining allows for it to be worn unbuttoned while still looking great. My only wish is that it were organic like most of Pranas clothing use to be and preferable not manufactered in China.
