Waterproof W7 Detachable Neoprene Neck Seal
Improve warmth and comfort on colder dives with the Waterproof W7 Detachable Neoprene Neck Seal. Designed for Waterproof W7 5mm and 7mm full wetsuits, this removable neck seal helps transform your wetsuit into a more effective semi-dry system by minimising water circulation around the neck.
It is ideal for divers who prefer diving without a hood but still want additional protection against cold-water flushing. The soft, flexible 2.5mm neoprene provides a comfortable fit, while the smooth-skin outer surface folds inward against the neck to create a closer seal.
The neck seal attaches securely to the W7 wetsuit using the integrated hook-and-loop fastening system. Its detachable design allows it to be easily fitted or removed according to the water temperature and your preferred exposure setup.
