This is the Kånken Classic, the design that Fjällräven launched in 1978 to spare the backs of school children. Shoulder bags were common at the time and back problems had begun to appear in increasingly younger age groups. The Kånken backpack soon became a common sight at schools all over the country. Today, it remains an excellent choice for school, outings or biking to work. The Kånken's large main compartment is opened by a U-shaped zip, which makes it easy to access your stowed-away items. There are also two side pockets, a zippered front-pocket and an internal pocket with a foam pad for comfort. Loopy haul handles, narrow shoulder straps and the round Fjällräven Kånken logo are other iconic features. Kånken is made out of durable, lightweight Vinylon F. Although a synthetic material (it is made of a fibre called polyvinyl alcohol), it has certain properties that are otherwise mostly found in natural materials.
