A major advantage of the Satch is the four important factors of a school backpack and the safety of your child. Satch considers ergonomics, individuality, sustainability, and visibility as these factors. Ergonomically shaped areas of the backpack are crucial for the development of a child's back. If the weight distribution is incorrect or something is pressing, it can cause significant damage. The Satch also features a design that allows the backpacks to grow with the child, accommodating heights between 1.40 m and 1.80 m. The Satch has large main compartments and an organizer in the front pocket for keys, cards, and more. It includes reflective elements that gather and reflect light. A Satch product is made from up to 100% recycled PET bottles. This is environmentally friendly and helps reduce waste in nature.
