A special feature of this backpack is the optionally detachable bottom compartment, which is perfect for dirty clothes or shoes, making it ideal for bike commuting. The bottom compartment can also be opened to create more space for larger items. The backpack also includes a 15.6-inch laptop compartment and a trolley attachment function, making travel even easier. The shoulder and back areas are comfortably padded, and there are practical attachment and compression straps, an additional zippered pocket for valuables, reflective elements, as well as a water bottle holder and a rubber band key/card holder on the shoulder strap. The durable material is PVC-free, water- and dirt-repellent, and resilient against the challenges of urban life.
