Jack Georges Voyager backpacks for business, travel, and every day use offer quality, function, and styling that stands the test of time. Each item is made from Certified Full-grain Buffalo Leather that is known for its superior strength and light weight. Minimal stretching of the leather during the tanning process ensures that the fibers remain strong and the unique character of buffalo shines through. Natural variations provide for a vintage look and feel. The leather itself is full-grain, using the best part of the hide. It is not corrected - the untouched grain allows the fiber to keep its full strength and durability. With a hand-stained finish, no two pieces will look exactly the same. Best of all, the leather will become more beautiful with time as it builds a rich patina that reflects how you personally use it.
