Me: 5''11", 160 lbs, 38-32-40, 34DD, thigh 22.5", calf 14". The XL fits me pretty well. I''m long-waisted, and it is a bit stretched in torso length, but quite comfortable. The sizing chart says XL will accommodate up to 5''10", but I think it would be OK up to 6''. The legs actually are a perfect just above the ankle bone length for my 33" inseam; inseam on the XL measures 29.5 while hanging on a hanger. It''s about 2" too big in the waist for me, but otherwise fits well and comfortably. If you are of normal height and have similar measurements, I would recommend sizing down to large, especially if you plan to get it wet. I use it for winter SUP, and really hope to never get it wet... LOL. While I love the relief zipper concept, I was concerned it would look awkward and feel uncomfortable. It''s actually fine, and bonus: totally prevents any camel-toeing plus is easy to use. I got a black swimsuit bottom to wear under it, and simply pull that to the side. Overall, this wetsuit is very comfortable for paddling and probably as good a fit as I''m going to find without buying a custom suit. I am well pleased.
