The BackPaq is a multifunctional bag that can be enlarged almost fivefold in size thanks to innovative twist technology. This means that the spontaneous, dynamic person can transform a bum bag or cross-body bag into a fully-fledged rucksack within seconds. The digital product passport (DPP) is used as an interface between the company and the customer in order to increase the product's recyclability. In addition to repair options and a return system, the functions and information of the BackPaq are mapped via the DPP.
