All my Volcom tanks fit a little loose but that's why I like them. 5'11" and about 175 and I get a large. I purchased two of these because I like the colors so much.bright Turquoise and Pewter. They seem to be the complete reversal on the site but the pictures are a little off. The turquoise is actually not as bright but the pocket on it is more black than you think. The pewter is pretty light grey as well.
