A favorite of school kids, hipsters, and vintage enthusiasts, the Fjallraven Kanken backpack can be recognized all over the world. With an old-school look and a huge variety of colors, there's for sure a Fjallraven Kanken pack that will let you either stand out from the crowd, or blend in a bit. Whatever you prefer. Personally, I've been trying to get Fjallraven to make a glow-in-the-dark Kanken backpack, so that I can really set myself apart from everyone else. They won't return my calls. The Kanken rucksack can be carried as a backpack or can be converted into a bag via convertible straps. Pretty neat, I know.
