There's no better way to boost warmth than to add a bibbed hood to your exposure protection gear. Layer it with any type of full-length or shorty suit for added warmth when diving. Thermoprene's natural stretch, about 75% more than standard wetsuit material, also means that this hood is easy to slip into or to layer with another garment without feeling any uncomfortable suit squeeze. Thermoprene material is both glued and blind stitched, which not only clamps down on water seepage, it also provides tremendous durability. A revolutionary new one way flow vent purge valve, vents regulator exhaust from the hood while preventing cold water entry. This design is a Henderson exclusive and not available on any other bibbed hood. Divers seeking a great value will appreciate Thermoprene's balance of performance and price. The latest technological innovation from Henderson, this new material delivers greater flexibility and improved features not found in standard neoprene wet suits, yet at a reasonable cost perfect for the cost-conscious buyer. The Henderson Thermoprene 3/2mm Bibbed Hood has a trim-able skin face seal, and anatomical fit. Hood is available in multiple sizes and is black in color.
