Fair enough, although I must admit I'm not convinced that Metzeler are only Hypalon.
- Plenty of folks on the ol' internet seem convinced they have a PVC Metzeler.
- They're listed under both the Hypalon and PVC sections on a number of websites.
- Looking through the valve I think the inside colour is similar to the outside.
- A few people reckon the construction/material changed when Zodiac bought them.
- The bloke in the inflatable shop today asked which one I have, implying there are more than one.
I do, however, know nothing about this stuff, so am willing to be schooled!
