Tire rubber certainly is a “supermaterial.” Although I feel it’s more suited to resisting wear and providing grip to F1 cars, it’s also tough, waterproof, and flexible when correctly manipulated. Tread has a lot of faith in the stuff, and has been repurposing South American waste tires to make all sorts of laptop bags, camera cases, and cell phone pouches. The prices are on the high end, but not ridiculous. They’ll probably last a long time as long as you don’t pour certain chemicals all over it and melt it.

If you’re looking for a unique look and like to gloat about your sustainable lifestyle, I think this is a pretty solid choice (These ones are pretty green too). They’d go really well with that gimp suit, too!
