The Fjallraven Rucksack No. 21 is a top loading backpack that features a drawstring cinch at the top, termed a snow lock by Fjallraven, just under the lid. The snow lock brings together the lighter weight canvas placed at the top of the backpack to help keep your belongings in place in an overstuffed pack. The lid on the Fjallraven Rucksack No. 21 borrows from Fjallraven’s best selling backpacks in the 1960’s and 1970’s. The lid features two leather straps that run through a leather loop or track on the lid; the leather straps then run through a metal loop on the body of the backpack and are then anchored in four different positions, depending on the load you are carrying in the backpack. The shoulder straps are a combination of the Fjallraven’s G-1000 fabric and leather. The straps feature a hint of padding within the fabric portion, while the leather section features 11 pre-drilled holes to allow the wearer to get a custom fit. The back panel of the Fjallraven Rucksack No. 21 has two strips of padding that run the length of the backpack.
