Wallets are the best place to store money and IDs, but the worst place to store packets of relish. Keep your condiments away from this Groupon.

Choose from a range of Mighty Wallet designs, each made from a single piece of durable, eco-friendly Tyvek—the material used for express mail envelopes. The wallets have no stitches, which tend to wear out, and adaptively expand to reveal two large pockets for cash and two pockets for credit cards. Their fibers are lightweight, recyclable, and water resistant.<p>

Dynomighty

The idea of a wallet made from Tyvek—the same material used for express mail envelopes—was so obvious to Dynomighty designer Terrence Kelleman that he assumed it already existed. But when a Google search yielded no results, he took advantage of the opportunity, creating his own wallet out of a folded piece of the eco-friendly, durable fiber. Each of the wallet’s tiny intertwined filaments is 50 times smaller than the diameter of a human hair, giving it tear-resistant strength even when it is wet or falls into the hands of a bodybuilding pickpocket. Wallets contain two expandable pockets for storing cash, two pockets for cards, as well as two quick access side pockets, and come in a choice of over 100 designs featuring TV shows, college logos, or quirky imagery. In addition to wallets, Dynomighty now applies their signature Tyvek design to tablet and laptop cases in a variety of graphics.
