Great shirt. Warm and comfy.
I'm 5'11", 190 lbs and fairly athletic. I ordered a large and a medium. I would have preferred just a slightly more slim fit from the large, but the medium was much too short for me. That's not to say that I'm unhappy with the large, which I ended up keeping. The quality is top notch, and the return process was very easy. If you're considering this shirt, definitely just go ahead and buy it. I will absolutely be coming back to buy more in the future.
