Well, some other people said that the small would fit me. The orange one doesn't have a medium anymore, but the blue version still has it. I like the orange one more, but if it won't fit me, I'll take the blue one.
I'd really have to get the right size on the first try, as it's kind of a pain to return it if it isn't right. I'm having it shipped to a friend in Atlanta who then ships it to me. Returning it will be a lot harder, I think.
Edit: I just looked at my Burton Poacher jacket which seems to be a small one. Maybe I should go with that?
