Add core and head insulation to your existing wetsuit with the Waterproof O1 Neoflex men’s hooded overvest. Its 5mm body and fixed 7mm hood provide extra coverage for cooler dives, while the flexible front-zip design makes it easier to layer over your main suit.
Features and benefits
- 5mm Neoflex body: four-way stretch microcell limestone CR neoprene lets the overvest follow the suit beneath it. Glued and blind-stitched seams help reduce water exchange.
- Fixed 7mm hood: double-layer protection in key areas adds warmth around the head. The Glideskin face seal sits smoothly against the skin and should be checked with your mask.
- HAVS venting: the Hood Air Venting System uses one-way valves to let trapped air escape, reducing the air pocket that can collect at the top of a hood.
- Inverted front zip: the YKK #10 Vislon zip finishes at the chest, leaving the face seal clear of the zip and giving your head more comfortable movement. The EasyGrip puller helps operation with gloves.
- EXTEND thermal lining: a soft, stretchy inner layer adds comfort when worn over the wetsuit.
- Detachable beavertail: double hook-and-loop fasteners help keep the vest from riding up. Remove the tail when the setup calls for it.
- Equipment grip: polyurethane surfaces at the shoulders and waist help keep BCD straps and a weight belt in position.

Care
