Product details:

The 3mm Hood is a full-featured 5mm wetsuit hood. Built to the same exacting standards as Pinnacle's 7mm hoods, the 5mm hood is ideal for divers who chill easily in warm water, cool water, and hearty cold-water divers. Hood is constructed from 3mm titanium lined nylon 2 neoprene throughout the hood and neck areas, has a large bib that tucks into wetsuit for a better seal and greater warmth, smooth-skin outer surface on bib creates seal against wetsuit, and 3mm face seal with smooth-skin seal. Smooth-skin, large bib, and face seal all keeping water out. The face seal can be trimmed to any desired size. Hood has a non-direct automatic vent that allow air to escape as necessary from the top of the hood while restricting water to re-enter. Hood is black in color and available in multiple sizes.
