When purchasing Lavacore, trying it on first is A MUST !!! I'm a guy, 6'1", about 175. I had tried on a couple of different mens pieces that "should have fit" according to their size chart, but they didn't. Or at least not the way I like my stuff to fit. On A whim, I was eyeballing another one hanging in my LDS, and it turned out to be a womens full suit. Well, guess what, I tried it on and the thing fit like a glove and that is the one that I bought and now wear. As far as the product itself goes, IT WORKS !!! I've been wearing under my 7 mil here in SoCal for the winter, and it certainly helps. You feel the cold, but you don't feel cold. It takes the edge/sting off the colder water. The past 2 months, I've been doing some deep/long dives and I've hit 50 degrees and was "comfortable".
