WATERPROOF Adult Unisex H1 5/10mm Polar Evoluted Hood, Size: L (WP-H1-5/10HAV-L)

The body reacts to cold by adjusting the blood flow to different parts of the body, like hands, fingers and feet. The body cannot adjust the blood flow to your head. This is to ensure brain function at all times. The colder it gets the more heat you lose from the head by radiation, or by conduction in the water. You stay warmer with an effective hood.

Waterproof's H1 5/10mm nylon-2 neoprene rubber hood with Waterproof's exclusive Hood Air Venting System (HAVS) is constructed with these scientific facts in mind and are proven to keep you warmer when you need it most. That's what Waterproof refers to as facing reality". Waterproof's exclusive HAVS uses double one-way valves to eliminate annoying trapped or build-up air caused by your regulator's exhausted air entering the hood. Hood features a 10mm double layered protection in critical heat loss areas.

The hood has an anatomical 3-D shape for a great fit with glide-skin seals, reflective logo, I-Span super-stretch nylon for easy donning. All seams are glued and sewn with bonded hi-quality nylon thread for strength and durability. Hood is available in multiple sizes and is black in color.
