Offering the best features of a bi-fold and a tri-fold wallet, the L-Fold Passcase wallet from Big Skinny features a quick flip flap for access to your most needed cards. It can hold more than 25 cards, and it features five extra-wide card pockets, two oversized hidden storage pockets, a full-sized, extra tall billfold area, and two ID pockets with clear plastic windows for easy access to your driver's license and work badge. The extra-wide pockets are lined with a rubbery coating to prevent cards from slipping out. Designed with rounded corners for comfort, it's constructed of a lightweight, water resistant nylon microfiber material that is 5 to 7 times thinner and lighter than leather. It's machine washable for easy care, and it dries out in about 20 minutes. The L-Fold Passcase wallet measures 4-1/3 x 3-1/4 inches (and 6 mm thin when empty). The first Big Skinny wallet was designed by Kiril Stefan Alexandrov (the company's founder) because he loathed sitting on a thick, heavy leather wallet. Since creating the original Sport Wallet in 2005 using an advanced nylon micro-fiber material (5 to 7 times thinner than leather), Big Skinny has added dozens of slim wallet styles for men and women with more on the way.
