The PORTER is ergonomically designed and grows with your child. It also helps your child easily keep track of notebooks, books, and writing supplies, maintaining order. The school backpack is customizable 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 secondary school. The PORTER school backpack has a storage capacity of 30 + 5 liters, divided into five compartments, including main compartments and book compartments. This ensures 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 at shoulder height and close to the back using the straps and compression straps on the sides. 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 like 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 and responsible manner without PFC and PVC.
