The Rolltop Backpack features a spacious main compartment that is easily accessible through a large opening. This offers the user a lot of flexibility, as the backpack can be closed in two different ways - either with a zipper or a high-quality metal buckle. The rolltop function of this backpack is particularly practical. The top part of the bag can be folded down as needed to increase or decrease the volume of the bag. This provides ample space and flexibility. In addition to the large main compartment, the backpack has two slip pockets and an exterior zippered pocket. These are ideal for storing smaller items that you want to access quickly. Inside the backpack, there is also another zippered pocket where valuables can be securely stored. Furthermore, there is a well-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 ensures high wearing comfort. The backpack also has a carrying handle and adjustable, padded shoulder straps that support the back and provide a comfortable carrying experience. The Rolltop Backpack is made from a recycled outer material, making it particularly robust and sustainable. The polyester fabric is made up of 50% recycled PET bottles. Additionally, the material is water-repellent, so rain cannot harm the backpack.
