Hypalon is a better material but this new German made PVC looks promising,
what do you think.

Where are you going to be using it? And how are you going to be storing it?
If you're not in the caribbean and are going to put a cover over it then
you're fine with PVC. If it's going to be sitting out in the blistering sun
365 days a year then you can't go wrong spending the extra money to get one
made of hypalon.
