The Ergobag Cubo school bag is ergonomic, customised, sustainable and visible from Year 1. Thanks to the wide pelvic fins, the weight is shifted from the shoulders to the stable pelvic area. As is popular with Ergobag, the Kletties allow the Cubo to be customised. Ergobag uses recycled PET bottles to manufacture the satchel in order to protect the environment. Matching safety sets can be added to the Cubo satchel for even more safety on the road. It has a sturdy base. Movement and posture influence body awareness and can promote personal development. Studies show that children who move a lot are more independent, sociable and motivated.
