The sports bag is a great complement to the Ergobag school backpack. This practical sports bag replaces a sports bag, the main compartment of the bag can be easily closed with a drawstring. A small external zippered compartment, located on the front of the bag, is suitable for storing various small items. Unlike older models, the sports bag can be easily attached to the Ergobag school backpack in 3 places, so that it is always securely attached even when the schoolchild moves. To produce this supplement, materials made from 100% recycled PET bottles are used.
