The Scout Roll-Top Backpack is a revolutionary design in the world of carbon-lined bags. A cavernous main compartment is complemented by a front pouch for additional storage. The roll-top feature expands to carry a high volume of goods while using a high-quality double carbon lining. Like our other bags, the Scout features rubber zippers, heavy-duty construction throughout, adjustable height and space capacity, new antimicrobial lining to protect carbon, an outer pocket for smaller goods and ultra-durable water-resistant fabric.
