An unusual ergonomic concept, ecological awareness, and style are the outstanding characteristics of the satch school bag. This innovative school backpack combines the concept of ergonomics used in modern trekking backpacks with the demands placed on school bags. Thanks to a back support system that allows for continuous adjustment, satch can grow with the child up to a body height of 1.80 metres. The fabrics used for the backpack are made from 100 per cent recycled PET bottles.
