An update to the popular Big Skinny Monte Cougar checkbook wallet, the Slimvelope tri-fold checkbook wallet holds everything you need while maintaining a sleek profile. This version of the Slimvelope features an exterior constructed of top grain cowhide leather and an interior made of Big Skinny's ultra-thin nylon microfiber material to help keep it thinner than a typical wallet. Big Skinny's "divide-and-conquer" design breaks up your cards into four discrete areas so they don't all clump together in one lumpy row. The Slimvelope features two checkbook-sized billfold areas, eight card pockets that hold three to five cards each, two ID pockets with clear plastic windows for easy access to your driver's license or work badge, a fully zippered pocket on the exterior and a magnetic snap closure. The extra-wide pockets are lined with a rubbery coating to prevent cards from slipping out. The Slimvelope wallet measures 7.5 x 4 x 0.27 Inch. 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.
