The 3mm Hood is a full-featured 3mm wetsuit hood. Built to the same exacting standards as Pinnacle"s 7mm hoods, the 3mm 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 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, keeping water out, and 3mm face seal with smooth-skin seal. The faceseal can be trimmed to any desired size; automatic vents allow air to escape as necessary from the top of the hood while restrictingwater to re-enter. Hood is equipped with reflective rear pattern for instant recognition and safety.
