Scuba Diving Hoods, Boots, and Gloves
Scuba diving boots, hoods, and gloves are typically made of neoprene, which contains tiny bubbles inside the material. These bubbles form an insulating barrier between your body and the water, proving excellent thermal protection. A thin layer of water will enter between the neoprene and your skin at the beginning of your dive, which is quickly warmed to your body temperature. In order to keep you warm, boots, hoods, and gloves must fit snugly, so that this warm water layer is not constantly flushed out by colder water.
