The Kanken has been around for a while, so it's not like you're going to be saddled with a pile of crap. But what makes the Kanken special is its quality and attention to detail. The construction materials aren't just good, they're great. Using a material called Vinylon F, Fjallraven created one of the best backpacks on the market.

There's not a lot to say about the Kanken, other than it is a very well made bag. There are several different styles of Kankens, from the laptop carrier to the Kanken mini for the little ones. There's also the Kanken rucksack, a bag for the kids with three straps and a zipper compartment for extras.
