We begin with our sturdy 18-ounce canvas, add quality roller buckles and then premium leather straps, sewn and reinforced with rivets. To our tough leather shoulder straps we added foam padding and covered the foam with soft glove leather. A clip-on sternum strap keeps shoulder straps from shifting, and an adjustable (and removable) hip belt further stabilizes the load and helps distribute the weight. The large side-release buckle closure on the waist belt makes getting in and out of the pack a breeze . In addition, we also added side straps for load compression and stabilization, side pockets, three slash pockets on the inside front and a deep inside pack pocket to hold a tarp or sleeping pad to cushion your back. Comes with a replaceable heavy-duty poly liner. Also available in Waxed Canvas. Made in USA.
