I love these shirts. I'm 5ft 10", 215lbs (including gut) and the large size fits the package well. It's a little tight at first, but loosens up after a few wears. I tried the XL size and like most Goodthread garments this meant it was about 2 inches longer and didn't really get any looser. It is worth noting that the sleeve openings are ribbed. So if you're looking for a looser sleeve, look elsewhere.
