Tyvek is an incredibly thin microfiber made with super fine plastic fibers that are 50x thinner than a human hair. This incredibly thin material is also super resilient and creates an original wallet design. Mighty Wallet is the first Tyvek® wallet design that began in 2005. The best wallets rely on the thinnest materials to give them the best slim features with a functional design. This is what distinguishes the Mighty Wallet with it's unique origami design using Tyvek.
