I’m 5’11 and 145lbs and the proteam stuff makes me look like a fatty, it’s a real tight fit, sometimes uncomfortably tight, plus I don’t like all these new long sleeve aero jerseys, they create wicked tan lines that a normal tshirt doesn’t cover. Classic stuff in small works best for me! It’s still snug and I can stand up and walk around without skin showing. I got a few pro team stuff buts it’s gilets and wind coats mostly.
