A backpack for all occasions: Weighing just 1,150 grams (without removable elements, total weight 1,250 grams), it is a true lightweight among school backpacks. With a capacity of 25 liters, it is just the right size. It features a large main compartment where your child can neatly store their school supplies. The spacious front pocket is perfect for delicious snacks, lunch boxes, and more. The water bottle fits best in one of the two outer pockets made of stretchy mesh material. On the front of the backpack, there are strap bands that allow your child to conveniently attach a jacket or helmet. Accessories like the tablet/laptop sleeve can be attached to loops in the main compartment, and the gym bag can be secured to the outside of the backpack. The JOKER grows with your child thanks to the Easy Grow System. A simple turning mechanism inside the backpack allows for easy adjustment of the shoulder strap height. This way, you can easily adapt the size while your child is wearing the JOKER. The padded shoulder straps, an adjustable chest strap, side compression straps, and a removable hip belt ensure a comfortable carrying experience. The JOKER comes with a patch right out of the box. Additionally, other style sets called "Colour Up" are available, featuring various designs, materials, and colors to add variety to the backpack - for a cool look that helps kids feel comfortable even after switching to a new school. The reflective strips and surfaces provide optimal safety in the dark. Another plus for environmentally conscious parents: all textiles are made from 100% recycled PET bottles. The JOKER is also climate-neutral, socially responsible, and produced with care - for a better future.
