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 insulation. It can only be used after training and is used for diving in cold areas.
In cold waters, dry suits are more common, but of course they are more expensive than wet suits, and they are mostly one-piece. Drysuits made of at least three materials, foam synthetic rubber, synthetic rubber and nylon. Dry suits are much higher than wet suits because of the need for special waterproof zippers and other accessories, such as a dry diving inflation vent (because air must be injected into and out of the dry suit to maintain neutral balance, so The drysuit has a line from the medium pressure port on the first stage of the regulator to the inflation of the drysuit). Using a drysuit requires special training to learn how to control and use inflation. The way to maintain and maintain the dry suit is to soak the dry suit in clean water and avoid sunlight 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 irreversible wrinkles from the foamed synthetic rubber.
The main function of the wetsuit is to prevent the body temperature from dissipating too quickly during diving, resulting in hypothermia. Secondly, the wetsuit can also protect the body from being cut by the reef and biological damage such as jellyfish and anemones.
Secondly, the wetsuit must fit well. The less seawater and the outside world are exchanged between the wetsuit and the body, the better the thermal insulation effect of the wetsuit. The most common wetsuit fabrics are nylon and lycra. The central lining of these two fabrics is foamed rubber, so as long as the thickness is the same, the wetsuits made of the two fabrics have the same thermal effect.
The difference between these two kinds of fabrics is in their surface fabrics, one is nylon and the other is lycra. Lycra has more threads per unit area and denser knitting, so it is more wear-resistant. In addition, the elasticity of Lycra is better, so the wetsuit made of Lycra will not deform.
Overall, Lycra wetsuits will last longer than nylon wetsuits. In addition, there is a non-functional consideration. There are many colors of Lycra fabrics on the market. Therefore, if you want to be dazzling in the water and be the best hero and heroine, Lycra fabrics will be a better choice. As for nylon fabrics, it can still have a place in the market, mainly because of its relatively low price.
