I'm thinking of purchasing the Orage TJ Pro Jacket.

From what I know, this jacket has a normal, non-baggy fit. I think a small/medium jacket would fit normally on me. But of course I want to look like a G. Nah mean? So I am lthinking of getting either an L or XL. If I go with the XL, is the jacket not going to keep me warm? Will cold air seep in the bottom? Are there any other problems with getting a super-large jacket that I am unaware of?
