Strong enough for the trail yet stylish enough for the city, the Fjällräven Rucksack No. 21 features a retro look inspired by the company's '60s-era bags. It's made from Greenland waxed G-1000 fabric and natural toned leather, and thanks to the waxed exterior it's both wind- and water-resistant. Up top, the cinching drawstring and lid are held down by padded leather straps with secure metal nubs. Down below, a durable leather bottom maximizes weight capacity. The exterior is finished off with a leather-embossed Fjällräven logo, two side pockets, and a padded back panel.
