The Big Boss Bags are hand made using only the finest materials. All of our bags are double stitched 1000 Denier Cordura canvas. The hardware is tough and durable to stand up to the toughest of environments. Our bags also feature an adjustment strap that helps the bag to be made into an easy-to-grasp shape and adjust the amount of elevation. By fully tightening the strap, it changes the height around 2.5 cm.
