This sweatshirt is a thicker sweatshirt and warm! I always wear a Nikita Hoody when I am snowboarding because they keep me warm with the high neck. I am 5'4, 110 lbs and have a longer torso so the XS I got comes slightly past my pant line. I would suggest getting a small if you are going to be doing a lot of activity in your jacket. This jacket is soft, comfortable, and looks good on. I have three of these jackets I love them so much!
