Filson introduced its Medium Rugged Twill Duffle over 30 years ago. It remains in the lineup for its durability and quality, even as the first of those bags remain in use. The exterior is crafted from industrial-strength Rugged Twill, sourced from one of England's most storied mills and lightly waxed for protection from the elements. Vegetable-tanned Bridle Leather is used for the handles, which extend around the bag to offer added support, and for the removable shoulder strap; both conform to the user's hands and body over time. A rust-proof, solid brass zipper secures items inside, while interior pockets on either endcap keep small items sorted. Finished with custom debossed, sand-cast brass hardware.
