I'm 6'1, 190, athletic, 33" waist. I ordered the L and wore it last season. It was very warm, easy (for a wetsuit) to get in and out, and very durable. The only challenge was it wasn't long enough in the torso and was either cramping my junk or riding up my rear all the time.So I ordered the XL this season. Same construction, same coloring, everything looked great. I put it on and the length was perfect on the legs, a bit long on the arms, and unfortunately, seriously disproportionately massive See full review
