Wetsui

Wetsuit
        A wetsuit is a special suit worn by people who want to spend a lot of time in the water. Wetsuits are usually worn by swimmers, divers, or surfers who swim in cold water. Wetsuits help the swimmers retain body heat. This, in turn, helps them avoid a dangerously low body temperature. Generally, wetsuits are made of rubber. The suit traps a thin layer of water between the rubber and the wearer’s skin. Body heat warms the layer of trapped water and helps keep the wearer warm. The wetsuit must be tight, or else the layer of trapped water will be too wide to keep warm.
