A Word of Warning
The first time I wore this base layer was while alpine skiing and I wore nothing under it. I will never make that mistake again. Let's just say by lunch both of my nipples were on FIRE! Something about this fabric is abrasive. I had to go to the car and swap out for another, as the pain was unbearable. Since then I've worn something underneath it and haven't had any problems. Very warm and feels soft everywhere else. Would recommend, just not as a first layer over the chest. I'm 5'9" 165lbs and a Medium fit great.
