The Ergobag Cubo is a backpack that always maintains its shape and is easy to handle. Even messy children can keep track of their belongings in school with it. It features a simple one-finger grip and a well-organized interior. Additionally, the Ergobag Cubo grows with the child. Thanks to its height-adjustable carrying system, the Your-Size-System, which accommodates heights from 100 to 150 cm, and the wide, padded hip fins, it offers high carrying comfort and adapts individually to the child's height. It is equipped with reflectors all around to ensure good visibility. The backpack also has a ticket pocket on the hip belt and can be easily opened and closed with a magnetic buckle. Made from 100% polyester (water- and dirt-repellent), it is produced from 39 recycled PET bottles. The 5-piece set includes a school backpack that combines the ergonomic concept of innovative trekking backpacks with the requirements of a school bag. A sports bag with a separate wet or shoe compartment, which can be worn like a backpack, is also included. Furthermore, there is a pencil case that can be equipped with 17 pens, an eraser, a ruler, a sharpener, and a timetable. The pencil pouch offers additional space for pens, scissors, and other essential items for school. The Ergobag Cubo can be customized according to personal taste with the 3 Velcro patches and the contour Velcro patch. It also features a loop for various hangies.
