Well known as one of Fjällräven's best-loved designs, the Kånken was originally produced for Swedish school children in 1978. Vinylon F fabric repels moisture better than any other, and convertible straps allow you to carry the Kånken as both a backpack and bag. And how can one resist the iconic Fjällräven name-and-address tag inside? This is a bag that will last you forever, and, let's be honest: It looks really cool.
