There is an element of surprise in the “Papier” series, a collaborative project between Saskia and Stefan Diez. One expects a rigid and fragile container but the bag is actually quite durable, water and tear proof. It looks like an art piece but it’s actually practical for frequent use. From their description:
… the “Papier” series is an experiment in revising the classical typology: the two designers have pointed out the basic requirements to a travel bag – durability, protection and light weight – and sought for an appropriate material other than the traditional choices of leather and reinforced textiles. The “Papier” bags are made of Tyvek®, a synthetic paper that is extremely lightweight – 135g for the bigger and 115g for the smaller bag. Apart from that, one will appreciate the high-end finishes applied to such seemingly banal material as paper. Silkscreen printing techniques gives it a particularly attractive look.
The “Papier” series won the German Designpreis 2010.
