The ideal companion for all elementary school students and teenagers in secondary school can be customized with Velcro patches and tags. That's why the Mate comes with a patch right out of the box. Thanks to the Easy Grow System, the Mate can be quickly and easily adjusted to your child's current back length. A simple turning mechanism with a corresponding scale allows for height adjustment of the shoulder straps. The weight can be distributed at shoulder height through the straps and compression straps on the sides, close to the back. The Mate offers plenty of storage space for books, notebooks, and everyday items. Four different compartments provide enough space for your child. The integrated book compartment is positioned close to the back to optimally distribute the load. The spacious front pocket has room for a snack box and more, while the two side pockets are perfect for a water bottle and umbrella. Additionally, the front is equipped with straps to securely store a jacket, helmet, or skateboard. These features, combined with 30 liters of storage space and a weight of only 1,250 grams (without removable elements, total weight 1,350 g), make the Mate a fantastic multi-talent. The existing reflective strips and surfaces ensure greater visibility in road traffic.
