Big Skinny's patented nylon microfiber material is about 10 times thinner and lighter than regular leather. Most Big Skinny wallets weigh 1 ounce or less versus 3-6 ounces for most regular leather wallets. That also makes Big Skinnies more comfortable to carry in a pocket or a bag because leather is so much heavier.

In fact Big Skinny's patented material is as thin as a regular business card--.21 mm! Because of the high tech patented nylon material and hours of research and design development, Big Skinny wallets will result in at least a 40% to 75% difference in size AND weight which make the biggest differences in wallet comfort.

Big Skinny's patented nylon microfibre weave is 230 denier density which makes it really durable and tear resistant—you'd have to cut it with scissors or a knife to get through it. Plus our patented nylon-microfiber wallets are 100% Vegan.
