Hi!

I am intrigued by the Sea-to-Summit reactor liner bags, but since the first thing I would do is rip open the back to make it play nicely with a top quilt, I'm thinking a cheaper solution would be to buy raw materials.

The are made of a material called "thermolite," and I can only find industrial website references. I don't know if there's a similar product from some other companies, but I'd like to buy a couple metres (yards, if that's how you roll) to play with.

Any leads?
