Perfect for front-pocket wallet carriers, the Curve bi-fold wallet from Big Skinny is designed with two-rounded edges to fit neatly in your front pants pocket. (It's also great for back pockets.) It features three card pockets, two extra-large hidden pockets, a full-sized billfold area, and an ID pocket with a clear plastic window for easy access to your driver's license or work badge. The extra-wide pockets are lined with a rubbery coating to prevent cards from slipping out. 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 Curve bi-fold wallet measures 4-5/8 x 3-1/8 inches (and 3 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.
