What does zip on mean?
Hello Wade, this hood is designed to zip-on to this suit: http://www.scuba.com/scuba-gear-43/154030/Pinnacle-Inferno-V-skin-Trilaminate-Merino-Mens-Wetsuit.html so you would be able to make this suit have an attached hood.
Pinnacle's new V-skin line takes all the technical features that Pinnacle has developed over the years and incorporates them into a layering system that will add significant thermal protection without buoyancy.
The V-skin line has taken Pinnacle's patented Merino™ lining to another level by incorporating it into a tri-laminate material with a microporous membrane and high stretch outer lycra. This highly technical combination of materials will form perfectly to the body without causing restriction; the form fit creates the perfect water layer held in place by the impermeable membrane. When out of the water the microporous membrane acts as a barrier eliminating wind chill while allowing excess heat and moisture to escape. With strategically placed highly breathable bi-laminate Merino™ panels the new V-skin line is the most comfortable and thermally efficient product on the market today.
The new Inferno is the latest innovation from Pinnacle; it separates the thermal component
out of the wetsuit so that it can be used in any watersports activity.
