Based on all the reviews, this seems like a great jacket and exactly what I'm looking for. My question is about the fit of this jacket: I have a TNF Denali fleece (as seen on college campuses everywhere, lol) in a size Large. It was given to me as a gift, but I think it's a little big on me and looks sort of floppy. I see from the reviews of the Resolve jacket that some people say to order up, so that would be a Large, I think, since the Large in the fleece seems a bit big on me..? Basically, I'm looking for your thoughts on sizing and, secondly, your thoughts on Backcountry.com's returns/exchanges - if I tried it on and wanted a different size, would an exchange be a big hassle? Thank you!
