Making adventure last since 1960

In the 1950’s, 14 year, old Ake Nordin from Ornskoldsvik in Northern Sweden spent more time outdoors than indoors. After many long treks in the mountains, Ake decided the backpacks at the time were unsatisfactory and took matters into his own hands by building a wooden frame. This evenly distributed weight across his back so the pack did not end up uneven, pear, shaped, and uncomfortable. It also meant he could carry more weight with ease. Ake’s innovation quickly caught on and in 1960 Fjallraven became the first to commercially make and distribute framed backpacks.

Fjallraven means Arctic Fox in Swedish, honoring the small and highly adaptable predator that lives in the Swedish mountains under the harshest conditions. From the small town of Ornskoldsvik, Fjallraven has now expanded to every corner in the world. The fundamental ideas remain the same; provide functional, durable, and timeless equipment to make the outdoors more enjoyable for all. We continue to find smart, innovative solutions to make every adventure an unforgettable one.


Ake built his first framed backpack in his basement with his mother’s sewing machine. Using strong cotton fabric for the pack, he attached the wooden frame using leather straps and used calfskin for the support straps. Not only was the pack more comfortable and distributed weight evenly, it also increased ventilation between his back and the pack. Soon after, during a trip up North, Ake’s invention caught the attention of the indigenous Sami people who spent weeks at a time high up in the mountains. They asked Ake to build them a backpack and after that a tent. Fjallraven had found its beginning.
