Hey there, I am a short guy - 5'7", but I've got a 41" chest. Medium? Just want to know if the coat has any give (like the sweatshirts).
A medium will be best for you. This jacket does not have any stretch to it.
I'm 5-9/5-10 and ~160lbs. I have the Medium, and it's a good fit with room for a sweater.
