I purchased this wetsuit for my son who is 5'9" and 140lbs. It fit him PERFECTLY once he got it on. But he had a VERY hard time getting it on at the leg and hand openings. So this may be closer to a Small/Tall size, but it's clearly labeled medium. He wore it one day on 3 dives. It's in excellent shape. I'm asking $25 plus shipping anywhere in the US.
