Diving hoods minimize heat loss from the head area, so if you tend to get cold after a time at depth there's no better fix than to add a hood to your dive suit. This updated 3mm hood with the bib is made of 100% high-stretch Everflex Nylon outside for maximum flexibility and durability, with an inside lining of comfortable plush. This new version features a face seal to cut down on water transfer, making it the perfect addition for extended warm-water dives.
