This jacket is amaazinggg!!! I'm 5'5" and 125lbs and bought a medium for layering. It fits perfectly! The sleeves hit around the middle of my hands and the length hits at the upper thigh. I haven't gotten a chance to take it out boarding yet (it's December and there's still no snow!), but I went for a long walk in below freezing temperatures and ended up unzipping it because I was sweating. I was a little disappointed in how flimsy the hood kind of seemed, but it's definitely been keeping me warm. The only downside is it doesn't have wrist gaiters, but I knew that buying it. Definitely check out this jacket!
