How much thinner and lighter than leather are they?
Usually 5-7 times thinner and lighter depending on the design and type of leather. Most Big Skinny wallets weigh 1 ounce or less versus 3-6 ounces for most leather wallets. That makes Big Skinnies more comfortable to carry in a pocket or a bag because leather is so much heavier. In fact Big Skinny wallet material is as thin as a regular business card–.21 mm!
