The Waterproof H1 5/10mm Sandwich Polar Evoluted Hood is designed for cold-water scuba diving. It uses a 5/10mm double-layer construction at key heat-loss areas and a sandwich face seal made from 2.5 mm neoprene with Glideskin on the inside and Smoothskin on the outside to create an effective seal around the face. The hood features the HAVS Hood Air Venting System with two one-way valves to evacuate air during dives, reducing hood squeeze and maintaining comfort. A 3-D shaped profile, combined with I-Spansuperstretch nylon and bonded hi-quality nylon thread, provides a durable, flexible fit for adult divers.

Designed for diving gear and compatible with full-face masks and standard scuba setups, this hood supports warmth and mobility for extended underwater sessions.
