A water-resistant duffle with saddle-grade Bridle Leather straps and handles. 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 Bridle Leather for the handles is strong and durable enough for horse tack, and extends underneath the bag to cradle the heaviest loads. 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 hand and shoulder over decades of use. The rustproof heavy-gauge zipper is built from solid brass and is reinforced with more of our saddle-grade leather. Sand-cast brass hardware is debossed custom for Filson. Construction details were carefully considered in this duffle bag, even those that are not obvious, such as the Tin Cloth binding on interior seams that prevents fraying and wear. Please see last photo for custom brand logo (symbolic of change) that makes this bag unique.
