The US Divers Mercury Shorty Wetsuit is a great way to keep your kids warm and protected during their time in the water. The US Divers Mercury Shorty Wetsuit does an exceptional job of maintaining kids core temperature while in cool and cold waters. It is designed to hold a thin layer of water close to the skin. This water is warmed by the body's heat and remains warm throughout the entire swim. The suit features a cutting-edge titanium blend chest panel that reflects heat back to the body.
