Diving suits are diving supplies, used to prevent the body temperature from losing too fast during diving, causing loss of temperature, and also to protect divers from reefs or harmful animals and plants.
　　 Wetsuit
　　Dry wetsuit
　　 When wearing a dry suit, the body is completely isolated from the water. Depending on the water temperature, you can wear a sweater inside to enhance heat preservation. It must be trained before it can be used for diving in cold areas.
　　In cold waters, the use of dry wetsuits is more common. Of course, they are also more expensive than wetsuits, and the styles are mostly one-piece. There are at least three types of dry suits made of foam synthetic rubber, synthetic rubber and nylon. Dry wetsuits are much higher than wet wetsuits because they must have special waterproof zippers and other accessories, such as dry diving inflatable and exhaust devices (because air must be injected and discharged from dry wetsuits to maintain neutral balance, so The dry suit has a pipeline from the medium pressure interface of the regulator stage to the inflation of the dry suit).
　　The use of dry suits must undergo special training, and learn how to control and use inflation №. The maintenance and maintenance method of the dry wetsuit is to soak the dry wetsuit in clean water and avoid sun exposure after diving, and store it in a ventilated and cool place as much as possible. The zipper should be lubricated frequently, and should not be folded for a long time to prevent the foam synthetic rubber from causing irreversible wrinkles.
　　The main function of the diving suit is to prevent the body temperature from losing too fast during diving, causing loss of temperature. Secondly, the diving suit can also protect the body from being cut by reefs and biological injuries such as jellyfish and sea anemones.
　　Secondly, the wetsuit must fit well. The less the seawater exchange between the wetsuit and the body and the outside world, the better the warmth of the wetsuit. Common wetsuit fabrics are nylon cloth and lycra cloth. The central lining of these two fabrics is foamed rubber, so as long as the thickness is the same, the warmth of the wetsuit made by the two kinds of fabrics is the same. 　　 The difference between these two fabrics is the surface cloth, one is nylon cloth, the other is Lycra. Lycra fabric has more threads per unit area and is more densely knitted, so it is more wear-resistant. In addition, the elasticity of lycra is better, so the diving suit made of lycra is less deformed. 　　 On the whole, the life of Lycra wetsuit will be longer than that of nylon wetsuit. In addition, there is another consideration that has nothing to do with functionality. Lycra fabrics are available in many colors on the market, so if you want to be dazzling in the water and be a good male and female protagonist, Lycra fabrics will be a better choice. As for nylon fabrics can still occupy a place in the market, mainly because of its relatively low price.
　　 Wetsuit
Wet diving suits are commonly used diving suits, made of foamed rubber, and generally have a thickness ranging from 1.5mm to more than 10mm. The cold water that penetrates is isolated by the clothes and will not permeate out. It will quickly become heated by body heat conduction. The isolation of active air bubbles can prevent the loss of body heat. The well-fitting wet-type diving suit can reduce the flow and exchange of internal and external water as much as possible, and the isolation effect is better.
　　Secondly, the wetsuit must fit well. The less the seawater exchange between the wetsuit and the body and the outside world, the better the warmth of the wetsuit. Common wetsuit fabrics are nylon cloth and lycra cloth. The central lining of these two fabrics is foam rubber, so as long as the thickness is the same, the warmth of the wetsuit made by the two kinds of fabrics is the same.
　　 This diving suit is made of foam rubber or nylon cloth and is worn next to the body. Wet wetsuits must fit snugly against the skin, and a small amount of water that enters is not flowing between the wetsuit and the skin to maintain body temperature.
