Designed by riders, for riders, this bag is packed with motocentric features including 2 large external pockets with dedicated, tool, hardware and additional gear storage. Two large internal pockets for securely stashing items like a fuel or water bottle. With 2 exterior zippers, these items can be accessed independently while the main compartment is fully zipped. In the back of the main interior compartment is a padded lap top sleeve with elastic retainers. The center compression strap cinches cargo down and these straps can be reversed and clipped to each other around the back of the bag and to help secure it to a sissy bar. Additional external straps help secure the bag to your moto and can be used to add a bedroll or jacket to the rear of the bag. A ventilated mesh back panel with molded bio-foam keeps some distance between your back and the pack which allows for air-flow. The bottom portion of the bag is PVC coated for water-resistance and easier clean up. Like all of our moto gear bags, we measure interior volume in a way that our customers can understand– 12 ounce beer cans. This backpack will hold 48.
