The thoughtfully designed unisex backpack is suitable for work, travel, and leisure. It meets the required dimensions for carry-on luggage on airplanes, making it extremely practical. The Classic Backpack M is a perfect complement to the Duffelbag M from the Rhombus Black collection. The spacious main compartment features a large 2-way zipper opening, allowing for easy loading and access. An additional zipper pocket on the outside provides quick access to your phone, passport, and other essential items. Inside the backpack, there is an easily accessible slip pocket that can hold a 13-inch laptop, as well as a zipper pocket for important items like your wallet. The rectangular base of the backpack ensures stability, and the quilted fabric keeps its shape. The well-ventilated mesh back offers excellent comfort even on hot days. The backpack features a carrying handle, and the adjustable, padded shoulder straps are gentle on the back and provide a comfortable carrying experience. The Classic Backpack M is made from durable and resource-saving material derived from recycled PET bottles—completely leather-free. This makes the backpack sustainable and suitable for long-term use. Additionally, the backpack is water-repellent, so rain is not a barrier.
