A wetsuit is a type of clothing specially designed for diving, swimming and water sports. It is usually made of an elastic material such as neoprene, polyurethane, or neoprene copolymer, which is waterproof, abrasion-resistant, and durable. Diving suits can be divided into full-body diving suits and short-sleeved diving suits. Full-body diving suits cover all parts of the body, including arms, legs and soles, while short-sleeved diving suits only cover the upper body. Diving suits are usually designed with a hood and a back zipper, which is easy to put on and take off, and can effectively protect the diver’s skin and reduce damage from marine life and other dangerous factors. Diving suits play the role of warmth and protection during diving, enabling divers to move in water for a long time, and are also an indispensable part of diving equipment.
