This has become one of my favorite jackets. Not to thick, but it's enough to keep me warm in 60 degree weather. Everyone's body is different. Revain says the model in this picture is 6'2" and is wearing medium, so that's what I ordered first, but it didn't fit me right, was to tight for me. I am 5'9.5" and 185 pounds, I ordered a large and it fits me just right.
