Fjallraven's Kanken Backpack dates back to 1978, designed as a solution to back and posture problems amongst Swedish school children. The same design returns in Frost Green, as it continues to reign as one of their most popular silhouettes. These hard-wearing rucksacks boast a generous 26L zipped main compartment, with a removable PE foam seat cushion in the back pocket to prevent objects from digging into your back, as well as serving as a handy seat for commutes or treks. The exterior hosts two flat pockets on each side, as well as a further zipped pocket on the front. Two carry options are offered by a sturdy top handle and ergonomic adjustable shoulder straps. The bag is finished with a Fjallraven rubber stamp applied to the front.
