Filson’s Twill Duffel is a rugged, versatile duffel that combines the qualities of Filson’s signature materials into one hell of a bag. It's engineered from an industrial-strength Rugged Twill fabric—a lightly waxed, tough-as-nails material designed to shrug off wet weather. Plus, multi-day trips are what its roomy pockets, spacious footprint, and gorilla-strong straps were built for.
