DURABLE YET COMFORTABLE DESIGN – We designed our 18"x10"x11" bag to be not only tough but comfortable as well. The backpack is made with reinforced double-stitched nylon seaming for long-lasting durability. The padded shoulder straps and lumbar area prevent discomfort and pain that can be caused by prolonged use. The hip belt with sturdy buckle keep the rucksack stable and secure while also helping to support the weight of the backpack.
