Just got mine today and quickly put it on. I got the XL, normally and XXL in shirts. But I bought it for an undershirt. Slim in the body and good room in the sleeves. I think if I had gone for the XXL it might have been too roomy. So now to decide on the black version. And, along with some others in here, I would like to see an unbleacher version so I can have it indigo dipped.
