I am 5'2" and a hundred pounds. I got the extra small. They fit me well. Fitted but not tight. The live chat guy told me to get a small which would have been huge on me. The problem is the snap in the front is tiny and not strong. There is also a little piece of Velcro that doesnt really do anything. It comes undone every time I bend at the waist. And then the zipper comes all the undone as well. I even tried wearing them with a belt and they still came undone. Two Buttons came off the first day of riding. The gaiters are to tight. Hard to fit over snowboard boot.
