Made with Filson iconic Rugged Twill and Bridle Leather, the Filson Original Briefcase is built to survive any workplace, whether on land, at sea, or in the air. The lightly waxed fabric sheds water and withstands abrasion, year after year. The handles and detachable, adjustable shoulder strap are built with the same Bridle Leather that's used for making horse tack. The roomy interior has organizational dividers and space for a 15 laptop and secures with a YKK® solid brass zipper protected by a storm flap. A testament to Filson's signature fabric's durability, one customer recorded over one million miles of travel with his Original Briefcase.
