Our Rugged Twill Large Rucksack embodies the philosophy that’s guided Filson for 125 years: Manufacture uncompromising products using the best available materials and construction. Products that withstand the rigors of daily use for years on end, that are handed down rather than tossed out. One of our first bags introduced more than 30 years ago, this traditional rucksack remains a testament to the idea that if a thing is worth doing, it’s worth doing right.

Rather than waxed canvas, Rugged Twill was chosen for its exceptional abrasion resistance. This industrial-strength fabric comes from Britain’s oldest, most storied mills, and is lightly waxed to keep valuables dry and protected from the elements. The premium Italian cow leather for the shoulder straps and reinforcing is strong and durable enough for horse tack. It’s been slowly vegetable-tanned over several weeks in natural plant-based solutions that transform top-grade cowhides into sturdy, supple, and lustrous leather that molds to the shape of your body over decades of use. The rustproof heavy-gauge zipper extends down the sides of the bag for easy access to contents, is reinforced with thick Italian cow Leather, and protected buy a large storm flap. The two front pockets are gusseted to expand for extra capacity and secure with snapped flaps. Sand-cast brass hardware is debossed custom for Filson.

Construction details were carefully considered in this rucksack, even those that are not obvious, such as the premium Italian cow Leather grab handle and the Tin Cloth binding on interior seams that prevents fraying and wear.
