Divers can underestimate heat loss under extreme conditions, combine this with new technologies allowing for longer dives and hypothermia can become a major problem. Waterproof created a series of accessories for their Polar Evoluted accessories line to help combat hypothermia in more extreme conditions. The Waterproof H1 5/10mm hood features a 10mm double layered protection in critical heat loss areas and glide skin seals for the neck and face. The Waterproof H1 5/10mm hood includes the unique HAVS (Hood Air Venting System) which uses one-way valves to vent annoying air buildup in the hood.
