Diving suits are divided into two types
Wetsuit: This suit is made of foam rubber or nylon cloth and fits snugly. Wetsuits must fit snugly to the skin, and a small amount of water that enters will not flow between the wetsuit and the skin to maintain body temperature.
Dry diving suit: When wearing a dry diving suit, the body is completely isolated from the water. According to the water temperature, the sweater can be used to strengthen the insulation. It must be trained before it can be used for diving in cold areas.
In fact, there is no difference between surf suits and diving suits. The materials and properties are similar.
