Our Rugged Twill Duffle Bags embody the philosophy that's guided Filson since 1897, making products that are handed down rather than tossed out. The bag is made from Rugged Twill, an industrial-strength canvas from Britain's most storied mills that is lightly waxed for water resistance. The durable Bridle Leather for the handles is strong enough for horse tack and wraps completely under the bag to cradle the heaviest loads. The solid brass zipper from YKK® is rustproof for a lifetime of dependable service. Tin Cloth canvas binding on interior seams prevents fraying and wear. Each interior endcap features a stow pocket for organizing smaller essentials and the Bridle Leather shoulder strap is detachable for hand carry. Custom sand-cast brass hardware.
