The PORTER is ergonomically designed and grows with your child. It helps your child easily keep track of notebooks, books, and writing supplies while maintaining order. The school backpack can be customized with Velcro patches and tags. Included in the package is a free patch to personalize the backpack. Additionally, coocazoo offers "COLOUR UP" patches with various designs, materials, and colors for a cool look that kids will feel comfortable with even after transitioning to a higher school. The PORTER school backpack has a storage capacity of 30 + 5 liters, divided into five compartments, including main compartments and book pockets. Everything is well organized and securely stored. It features a front pocket and a compartment in the hip belt, perfect for small items like coins, headphones, or gum. Does your child need more storage space? No problem! The PORTER has an additional 5 liters of capacity. Simply open the back zipper to create extra space in no time. The PORTER prevents unnecessary strain. Thanks to the EASY GROW SYSTEM, it 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 through the straps at shoulder height and the compression straps on the sides close to the back. The PORTER is also smartly designed: the tablet/laptop pocket can be attached to the loop in the organizer compartment or clipped into the book compartment, depending on the size. Other items, such as a jacket, bicycle helmet, or skateboard, can be attached to the straps on the front of the backpack. By the way, coocazoo backpacks are produced in a climate-neutral manner and responsibly without PFC and PVC.
