I would find out what the three layers of "material" are. If it's Hypalon like my Achilles inflatable then I'd go for it. That stuff is nearly indestructible and holds up to UV. If its PVC like my old Zodiac inflatable then it's pretty good. Doesn't last like Hypalon but is good stuff. If it's vinyl then forget it at that price.
