Designed for full-face mask users in scuba diving and diving gear setups, the Waterproof H2 5/10mm Sandwich Venting Hood provides warmth and protection in extreme conditions. The 10mm double-layered neoprene in critical heat-loss areas delivers targeted insulation while maintaining flexibility for comfortable movement underwater. The hood incorporates a Sandwich Face Seal and Glideskin seals at the neck and face to create a secure, watertight fit during dives. As part of the Polar Evo series, it is built for cold-water performance and durability. The Hood Air Venting System (HAVS) vents trapped air to reduce buoyancy shifts and flushing, supporting uninterrupted dives. A super-stretch nylon outer shell and bonded high-quality nylon thread contribute to long-lasting durability, while an extended lining adds warmth in key zones. A reflective logo enhances visibility in low-light conditions for safer diving experiences.
