This website isn't called Big Skinny without a reason. All the wallets featured on this website are some of the thinnest in the world, thanks to innovative technology that includes ultra-thin nylon microfibers that surround the contents inside each wallet. Each design features wonderful technology so that you can feel at ease when placing this wallet in your pocket on the go without creating an unnecessary bulge. Eliminate the possibility of being victimized by a thief who sees the bulge and assumes there's something big inside. With dozens of styles and designs to choose from, including check book wallets, cell phone wallets, money clip wallets, and more, there is something for everyone. Tri-folds and bi-folds are available, along with nylon wallets that are machine washable, and leather ones that create a more classic look.
