im not trying to plug these guys, but has anyone else heard about silicone seals? in theory it should hold up much better...





Waterproof's new wrist and neck seals far exceed current latex products and are sure to set the standard for all drysuit divers.

Seal System Features:

# Hypoallergenic medical grade silicone - no latex allergy
# 40% more stretch than latex seals
# Extreme durability – UV, Ozone and Chemical resistance
# Superior Tear Resistance
# Ease of Donning/Doffing – no talc or powder necessary
# Easy replacement as required using SI TECH Quick Exchange System

i just heard about it today, so i havent looked for any reviews yet

Silicone cannot be glued to dry suits so a zip type attachment has to be the method of attaching it to the dry suit.  Here is a short review

They are designed to be used in conjunction with si-tech ring systems.  I've purchased both the silicone neck seal and the si-tech neck nite rings, but am having a hard time figuring out how to install the neck ring on my DUI.  If anyone has a suggestion, it would be appreciated.
