The Waterproof W7 detachable 2.5mm neck seal adds a closer neck seal to compatible W7 5mm and 7mm full wetsuits. It is particularly useful when diving without a hood and you want to reduce water moving through the collar.
Features and benefits
- 2.5mm flexible neoprene: adds a soft sealing layer around the neck without a full hood.
- Fold-in smooth skin: the smooth outer surface folds inward against the skin to restrict flushing through the collar.
- Hook-and-loop attachment: attaches to the corresponding W7 fitting points, making the seal easy to add or remove as your setup changes.
- Dedicated size ranges: men’s and women’s versions match different neck measurements and W7 suit cuts.

Fit and use
Measure around the base of the neck and choose the matching range and suit cut. The seal should sit closely without excessive pressure. It reduces water exchange but does not turn the wetsuit into a drysuit.
Care
Rinse after use and dry in the shade. Keep the hook-and-loop fasteners away from the smooth sealing surface and follow the suit’s care guidance.
