The Tighties Minimalist Wallet boasts twice the functionality of most other minimalist wallets, in half the size—making it literally the most minimal wallet we’ve come across. Its weather and water proof expandable molded material can easily fit up to 17 cards and some cash, while its key loop allows for securing the wallet and keys to the rest of your gear, belt, or a lanyard.
