What is wetsuits

From Wikipedia.org :

A wetsuit is a protective garment used for watersports such as scuba diving, surfing, windsurfing, kitesurfing and triathlon.

A modern, warm-water wetsuit is mostly made from thin open-cell neoprene, which provides limited thermal protection for activities in cold water, but protects the wearer in warm water from sun exposure. Cold-water wetsuits are built differently, have seams which do not leak, and provide good protection from cold water (to about 45°F, or 8°C) for up to 60 minutes in shallow water (less than 10 meters or 33 feet).

A synthetic rubber named Neoprene used to build wetsuits, since neoprene trap water between the wetsuits and the wearer. The water circulation on this layer, reduce body heat loss while the wearer doing water sports activities like scuba diving and swimming.
