I went big, I like to stuff my downy under it when I get done skinning. I'm 5'4, 36 chest. I ordered a medium at first, it fit nicely but I really like the room for my shoulders and chest (and downey) with the large. Not too wild about the thumb hole wrist things but you can slide them up and they're not noticeable. All pockets are awesome! I like the deepness and the low positioning of the front two as well as the inner and outer chest pockets. The arm pocket is sweet for using a lift pass that scans. Powder skirt has two side loops but nothing for the back, the butt is where the snow goes, at least for me. This is my biggest complaint about the jacket, I am very happy with it regardless.
