Got mine yesterday. It is nicer than the pics show. The back has the opening like the fishing shirts, for evaporation/breathing. The body and arms are long in the XL. While not "tight" the belly of XL is pretty filled up with my 260# on 5'11"/6' frame with a t-shirt under it

The tag says "eliotex", is that the same as Insoltex? I am guessing so, as it looks the same. It is very thin and comfy, and not noisy. Glad I got it, will use it this weekend deer hunting.
