I have this shirt, and the Cloudchaser Hooded shirt as well. I use them for snowboarding, hiking and camping. They are warm, but also have excellent breathability in the right spots. I have gotten rid of all my other base layers and use only these for snow sports. The fabric is soft and comfortable, and easy to care for with basic washing. I am 5'3" and curvy/D cup. I have the Pinnacle in large and it fits nicely - not too sung, but hugs in the right places, and I have the Cloudchaser in XL which it fits loosely and comfortably for the days I want to wear only an base layer and no jacket. Highly recommend, and will likely buy another because I wear them both so much.
