and the Avon division of Zodaic uses hypalon. Wing Inflatables, a small company out of Arcata, California, does some interesting stuff for the military. I set next to the owner, Bill Wing, on a flight out of Arcata a few years ago and we spent the time talking about the recreational/cruising market. I can't wait for him to get into this market and from his web site it looks like he might be heading in that direction. He uses a poly type fabric that you can shoot a 22 caliber bullet at and not put a hole in it. It's poly but with better UV protection then a Zod. He told me that all he would have to do for the cruising market was to remove some of the "Ninja knife holders and gun mounts". :-) http://wing.com
