Straight backs are healthy backs. Fjällräven launched the Kånken in 1978 to help prevent posture problems among Swedish schoolchildren. The backpack quickly became indispensable in conventional and forest kindergartens across the country. More than 35 years later, Fjällräven's bestseller has saved millions of children from spinal damage. The classic's success continues to this day, not least because the backpack performs just as well on the way to school and work as it does on outings and trips. The backpack is made from durable, lightweight Vinylon F, which repels dirt and moisture. Thanks to the large zip opening, the spacious main compartment is easy to pack. The two flat side pockets and the zip pocket on the front are ideal for items that need to be quickly accessible on the go. The PE foam seat cushion can be stored in the rear interior pocket when not in use, preventing the contents of the backpack from pressing against the back. When it's time for a break, it can be quickly retrieved. The simple yet practical carrying system consists of handles on the top and narrow, adjustable shoulder straps. The logo on the front is reflective. Inside the main compartment, there is an address label.
