The Rolltop Backpack has a spacious main compartment that is easily accessible through a large opening. This offers the user a great deal of flexibility, as the backpack can be closed in two different ways - either with a zipper or a high-quality metal buckle. The roll-top function of this backpack is particularly practical. The top part of the bag can be folded down as required to increase or decrease the volume of the bag. This gives the backpack plenty of space and flexibility. In addition to the large main compartment, the backpack has two slip pockets and a zippered compartment on the outside. These are ideal for stowing smaller items that you want to access quickly. There is also a further zipped compartment inside the backpack, in which valuables can be safely stored. There is also an easily accessible, padded laptop compartment that can accommodate laptops up to 15.6 inches in size. Another feature of this backpack is the mesh back, which makes it very comfortable to carry. The backpack also has a carrying handle and adjustable, padded shoulder straps that are easy on the back and comfortable to wear. The Rolltop Backpack is made from a recycled outer material, which makes it particularly robust and sustainable. The polyester fabric is made from 50% recycled PET bottles. The material is also water-repellent, so that even rain cannot harm the backpack.
