Some of our most enthusiastic customers are men who have been sitting on a thick, heavy leather wallet for decades. After extensive research, we have crafted the world's thinnest, lightest, most comfortable and most durable wallets. Crafted from our proprietary light-weight and water-resistant nylon micro-fiber material that is five to seven times thinner than leather, you're sure to feel a difference with our wallets. In fact, Big Skinny wallets end up THREE to FIVE times thinner and lighter than a regular leather wallet with the same amount of stuff in them. And this is not your 70s style nylon wallet either, our modern thin wallets are designed for generation now. Everything in your life is high tech so your wallet should also be.
