One of Big Skinny's most popular wallets, the perfectly balanced Slimline bi-fold wallet is designed with just enough unique slots to access your most frequently used cards in an ultra-thin package.

This version of the Slimline bi-fold features an exterior constructed of top grain cowhide leather and an interior made of Big Skinny's ultra-thin nylon microfiber material to help keep it thinner than a typical wallet.

It features a full-sized billfold area, four credit card pockets, an ID pocket with a clear plastic window for easy access to your driver's license or work badge, and two oversized hidden storage pockets -- enough storage to keep up to 25 full- sized plastic cards.

The extra-wide pockets are lined with a rubbery coating to prevent cards from slipping out.

The Slimline bi-fold wallet measures 4-1/2 x 3-3/8 inches (and 4 mm thin when empty).
