The primary purpose of a wet suit is to provide thermal insulation and protect the body from cold water. Wet suits are made of neoprene, which contains tiny bubbles that trap water and provide insulation. When a diver puts on a wet suit, some water enters the suit and is warmed by the body’s heat. This creates a layer of warm water that helps to keep the diver comfortable in cooler water temperatures.
In addition to thermal insulation, wet suits also serve to protect the skin from scrapes, stings, and sunburn. However, while these aspects are important, the main function is focused on insulation, especially in colder diving conditions. The design and material contribute significantly to preventing hypothermia, which can be a serious risk during prolonged exposure to cold water.
Although buoyancy control is essential for diving, wet suits do not provide significant buoyancy assistance. Instead, they can create a slight buoyancy effect, but divers typically rely on buoyancy compensators for precise buoyancy control. Lastly, while some divers may choose to wear wet suits for style or personal preference, fashion is not a primary function of wet suits in the context of diving safety and comfort.
