Im 5-9 and 160lbs, and I have several wetsuits, because I love to mix and match, since I mostly dive the Florida springs and a nice, clear freshwater lake here in my home state, which I dive, snorkel also. The temp in the springs and lake I snorkel/dive are anywhere from 68-72 degrees. I have a Henderson 3m JS, a Henderson 5m JS, a Henderson shorty 3m front zip, a Henderson shorty 5m front zip long sleeve, and a Henderson 1.5m JS. I mix and match and layer all of these according to the situation. I also have a Henderson 3m vest I use also. When my torso is covered, Im usually fine. For the springs, I mostly layer the 1.5m with the 3m shorty, and Im fine. Sometimes I use the 5m long sleeve shorty or one of the JS the 3 or the 5, and use a shorty(layer) accordingly. Lets just say I have options, and want it no other way.
