What's a ruck? It's a style of pack where you just carry your essentials, not your favorite teddy bear. But, since this ruck has a roomy full-access interior with three exterior pockets, you can fit what you need and a little more (with no bear left behind). A Bridle Leather carrying loop and adjustable straps, along with a rustproof zipper, makes the Filson Rucksack ideal for around-town excursions.
