Straight backs are happy backs. Fjällräven's Kånken was launched in 1978 to spare the backs of school children. Back problems had begun to appear in increasingly younger age groups and shoulder bags were popular. Kånken has many simple, clear functions. The backpack soon became a common sight at pre-schools and nature schools around the country. The idea of using a backpack quickly spread, as did Kånken. It is just as popular today, and an excellent choice for school, outings or biking to work.
