- Wetsuit Protection
Wetsuits not only keep you warm, but are your first line of defense against environmental conditions. In California, most divers opt for 7mm thick neoprene to resist the cold water temperatures. Some divers who are often cold go for full suits with hoods built in, where others might use separate hoods with their suits. Vests with hoods are also a convenient way to add an extra layer of protection when the water is especially chilly. Another important consideration is the zipper system. Some suits offer a “self donning” design, so you don’t need a buddy to zip you up before each dive. Divers headed to tropical dive sites go much thinner, down to 3mm. "Shorty" style wetsuits are liberating and comfortable in warm water dives, but don't offer any protection against jellyfish stings.
