Zipper is an innovative schoolbag for first-year pupils. The schoolbag is child-orientated and playful, thanks to constant contact with first graders during the development of the project. It has a new belt system that gives the bag a better fit. The back area is made from EPP, which is shock resistant and ajusts itself to the shape of the spine. The vertical zipper is a unique detail that comes together with a hoodie-concept. This allows you to wash and change of the outer skin. This concept is currently being continued by a Bernese company.
