Fjallraven Kanken Laptop 17 Backpack Vinylon F Travel School Bag Black The Fjällräven Kånken Laptop 17" Backpack in Black is a specialized, larger version of the iconic Swedish daypack, specifically built with a dedicated, padded rear compartment to protect a 17-inch laptop. Contrary to the "vinyl" label often seen in retail shorthand, it is actually crafted from Vinylon F, a proprietary, highly durable synthetic material that mimics natural fibers by swelling when wet to naturally repel water without relying on harmful chemical coatings.
