I'd also avoid Montbell--their sizing runs really small. I am a (OOPS--EDITED) 5'3",150# woman and their women's size Large is a snug fit. Their clothing is made for slender Japanese folks. It's wonderful stuff, but not for you!

For whatever you order, check size charts carefully and be prepared to send stuff back if it doesn't fit. An extra $10 return shipping charge is cheaper in the long run than clothing (or any other gear) that is the wrong size!
