The H1 5mm Hood features a 5mm double layered protection in critical heat loss areas and glideskin seals for the neck and face. Waterproof H1 3/5mm includes the unique HAVS (Hood Air Venting System) which uses one-way valves to vent annoying air buildup in the hood.

Waterproof make no excuses for the quality and spec of their dive range which doesn't make for the cheapest product but the H1 3/5mm neoprene wetsuit hood is certainly worth it. Another quality product from the Swedish brand "Waterproof" - the dive brand synonymous worldwide for their superb quality dive products and innovative design. "Waterproof" is the brand name - it does not mean the wetsuit dive hood is waterproof!
