On average, they're five times lighter than other wallets. That's because Big Skinny's wallets are made with proprietary nylon microfiber that's thin, but tough. If you drop one in a puddle, just throw it into the washing machine and air dry. Try that with your old-fashioned wallet. We also have hybrid leather wallets made with premium cowhide leather on the outside and nylon microfiber on the inside, so they're still skinny. We made the pockets inside our wallets extra wide, so you won't have to slowly coax out a card you need in a hurry. Our wallet pockets also have non-slip linings to prevent your cards and cash from spilling onto the ground when you open up or drop a Big Skinny.
