Waterproof Silicone Neck Seal Silicone Neck Seal for use with the Waterproof Neck Seal kit. Latex is history! Waterproof developed the Silicone Seals - for too long latex seals have been the biggest problem in drysuit diving: You are never sure what state they are going to be in until you open your dive bag and they are easy to rip and prone to deteriorate from factors such as the sun/UV rays- chemicals and ozone. The Silicone Seal will set a new industry standard. With Waterproofs new Silicone Seal there is no chemical or environmental sensitivity and they have 40% better stretch than latex seals. The elasticity makes donning the suit much easier and it seals with your skin more effectively. The comfort really is enhanced during long technical dives and decompression stops.
