Review on Full Body Lycra Skin Snorkeling Wetsuit by Phantom Aquatics by German Diaz

My wife and I used this snorkeling in Hawaii. They offer good sun protection and enough heat retention in the water that even after about an hour in the water we didn't feel chilly, unlike our fellow snorkelers who got so cold they had to get out of the water. It gets pretty hot in direct sunlight by the time you swim (because they're black, and that was in Hawaii!), but the front zip makes it easy to cool down. This is not a substitute for a swimsuit (opaque and VERY form fitting). Stretches well, the seams are not too tight.
