Wet suit is the most commonly used diving suit, made out of foam rubber, general thickness from 1.5 mm to 10 mm above, into the cold water was cut off clothes won't permeate out and by body heat conduction, heat up quickly, by the isolation of active air bubble, can prevent the body heat loss, fitted wet diving clothes, can make the internal and external exchange as much as possible to reduce the flow of water, better the isolation.
A wet suit must be fitted, and the less water is exchanged between the suit and the body, the better it will be. The most common types of diving suit are nylon cloth and lycra cloth, both of which are made of foam rubber in the center of the cloth, so as long as the thickness is the same, the two types of diving suit have the same thermal effect.
The diving suit is made of styrofoam rubber or nylon and is worn next to the skin. Wet suits must be fitted to the skin, and the small amount of water entering the suit remains stagnant between the skin to maintain body temperature.
