Waterproof H1 5/10 SANDWICH – Polar Evoluted
Designed for the harshest cold-water diving environments, the Waterproof H2 5/10mm Sandwich Polar Evoluted Hood delivers exceptional thermal protection, comfort, and performance. Built specifically with full-face mask divers in mind, this premium hood combines advanced insulation technology with a unique face seal design to create one of the warmest and most comfortable diving hoods available.
The H2 Sandwich Polar Evoluted features 10mm double-layered neoprene in critical heat-loss areas and 5mm neoprene throughout the rest of the hood, providing outstanding warmth during extended cold-water dives, technical diving, commercial operations, and expedition diving. The hood is constructed from 100% Microcell Limestone CR neoprene with super-stretch nylon for a secure yet comfortable fit.
Perfect for Full Face Mask Diving
What sets the H2 Sandwich Polar Evoluted apart is its innovative sandwich-constructed Glideskin face seal. Unlike traditional hoods, this design is specifically engineered to work seamlessly with full-face scuba masks, creating an effective seal around the mask skirt while minimising water ingress. This helps maintain warmth, improves comfort, and reduces flushing in cold-water conditions.
The integrated HAVS (Hood Air Venting System) uses one-way valves to automatically release trapped air from the hood. This prevents uncomfortable air pockets, improves fit, and eliminates the “ballooning” effect often experienced when using full-face masks or during frequent mask clearing.
Whether you’re diving with an OTS Guardian, OTS Spectrum, Kirby Morgan, Interspiro, or other full-face diving mask systems, the H2 Sandwich Polar Evoluted provides the warmth and sealing performance needed for demanding cold-water operations.

Rinse your hood after each dive with freshwater. Other cleaning products may only be used if authorized by Waterproof.
Store your hood away from sources of heat and away from sources of UV radiation (mainly sunlight), as both of these may degrade the materials more rapidly.
