Whether you dive for work or recreation there is nothing that can ruin the experience quicker than feeling cold. A wetsuit encases the diver's body with a layer of foam neoprene providing warmth and also protection from stings and abrasions. A wetsuit works by allowing water to enter the wetsuit and the body heats the thin layer of water next to the diver's body. The result is the diver is wet, but warm. The fit of your wetsuit is essential as the more you can minimise the water movement between your body and the outside ocean the less heat will be lost.
