Simple and stylish gray T-shirt with a pocket, casual design. - Brand: URBAN RESEARCH DOORS - Size: 38 - Material: 100% Cotton / 55% Polyester / 45% Polyester Regarding the size, I selected M because it says 38, but I think it's a rather small, compact type. The main body is 100% cotton, so it feels good against the skin. This T-shirt is easy to match with any style. I'm selling it because I outgrew it before I wore it much. Thank you for looking.
