I got a small and it's the perfect length (I'm about 5'10). It isn't too tight or too loose and has a feminine fit. Not bulky but plenty warm. It keeps me at the perfect temperature whether hiking, snowboarding, or peak bagging. I love the sleeves with thumb holes and the powder skirt works great. Not to mention plenty of pockets! All in all, a great purchase.
This jacket is great! It is comfortable, completely adjustable, and not to mention very classy. It has linings in the sleeves that can hook over your thumb for extra protection. And I really like the inner seam that can snap around the waste so when you biff it or slide, snow wont go up your back. It also helps that the jacket is a little bit longer. It is definitely designed with snowboarders in mind. I ended up buying the medium size and I am 5'6" and fairly average. It fits comfortably and I can still layer underneath. This jacket was a hell of a lot cheaper too than buying a similar one from REI. Seriously, its a good deal.
