Product Information
The Waterproof Neoprene Neckseal is a superstretch neoprene drysuit neck seal made of Yamamoto superstretch 4000 Neoprene for cold water dives. It fits WP, SI TECH Neck Tite and SI TECH Quick Neck seal systems, and is sold under manufacturer article number 781-10X-00 in unisex sizes based on neck circumference.
Who it is for
This is for drysuit divers who dive in chilly water and want insulation at the neck rather than a bare latex seal, and for anyone running a WP, SI TECH Neck Tite or Quick Neck interchangeable seal system who wants a neoprene option on hand. Because the seal swaps into those ring systems, it also suits divers who like to change seals between cold season dives and milder conditions, or who want a spare neck seal in the travel bag for extended days in the water.
Key details
- Material: Yamamoto superstretch 4000 Neoprene
- Fit: unisex, sized by neck circumference
