This small and lightweight transport bag for backpacks up to 80 L protects backpack straps and buckles from damage, dust, and splashes during transport (these often get torn off, especially in airplanes). Its compact size makes it the ideal travel companion and can also be used as a dirty laundry bag or as a second piece of luggage. The roll-top closure allows it to fit any size backpack (up to 80 L) and can be carried with it. It also features a removable shoulder strap. The protective bag is coated and therefore also offers protection against splashes.
