Straight backs are happy backs! Kånken was created as early as 1978 to help prevent back problems among Swedish schoolchildren and quickly became commonplace in preschools and nature schools across the country. Today, 35 years later, Kånken has straightened millions of backs around the world and has become one of Fjällräven's most beloved products. This classic backpack is equally suited to commuting to and from school or work, as well as hiking and traveling.
