I can't find anything anywhere else in the community.. how do the pullover hoodies run? I want to get one for a friend as a gift and he says he wears medium, but I'm afraid that it may not fit him right. My dad has a pullover hoodie from Woot from last winter, I think it was medium as well, and he says it fit a little tighter. The guy I want to get it for, while still fairly skinny, is a little bigger than my father. I don't want to get something that will be too tight, but at the same time I'm afraid if it's too big he won't wear it, so I'd like to get a medium if I can..
