More precisely: made of Kraft paper. In order to further maximize the sustainability of our products, we are continuously experimenting with new materials. The result is the KRAFT-collection. This combines a new type of vegan leather, which is practically indistinguishable from the beautiful structure and feel of real leather, with the environmentally friendly kraft paper. The kraft paper is made from natural plant fibers and is characterized by a high level of sustainability in raw material extraction and recycling. In addition to the clear ecological advantages, this extraordinary material is a real eye-catcher and also as lightweight as a feather compared to conventional backpacks. Nevertheless, this innovative material is tear-resistant and robust as well as water-repellent – just as you can expect from a backpack.
