Replacement exposure blankets

Hey Everyone,

I want to replace my exposure blanket and want to find out if I'm buying the right material. Is it closed cell neoprene? Like wetsuit material? Anyone know a good source for replacements?

Thanks!

I used pond liner from Home Depot.

Cheap and works great. I replaced the seal around the edge with silicone I believe.

Give it a try!
