Perfectly fitted and insulated wetsuits are the most common and polyvalent thermal protection for waters between 50 and 86°F (10 to 30°C). Their principle is to trap a thin layer of water - which the diver's body will heat very quickly - between the suit and the skin. This insulation system allows the diver to retain some heat even when wet. Beuchat wetsuits are adapted to the body shape thanks to the addition of panels and elastic reinforcements promoting the flexibility of movement.
