Silcone Drysuit seals
Drysuits are necessary for Scuba diving here in Southern California; the water is cold, usually about 55 degrees. Drysuits however are not cheap, $2000 to $3000, and require annual maintenance to keep them in tip top shape. The majority of this maintenance is the sealing surfaces around your neck and wrist. The current seals are made of latex, they work but are easily ripped and once exposed to sunlight or ozone, they start to deteriorate. It can cost as much as $100 to $200 to replace the neck and/or wrist seals.
Silicone apparently is the proposed answer from a Swedish company called Waterproof.
Super stretchable, impervious to sunlight and strong. I’ll let the video speak for itself, the looks nice and they have the added benefit of not needing any talc or lubricate to don.
Here is a video where a representative from Waterproof shows them off.
I just hope I can get some for my DUI drysuit eventually.
