The Mighty Wallet is made from Tyvek. That's the same material used for express mail envelopes. This means that it won't tear, won't stain, and is water-resistant. Two fun styles are available.
This wallet can take a beating. Made of Tyvek, it is water, stain, and tear resistant, and it's expandable. Oh, and it comes in cool designs too. Buh-bye, boring leather.
