When we introduced our Original Briefcase in 1994, our mission was clear: use the best materials available to manufacture a briefcase that would live up to our legacy of providing customers with gear that stands up to the rigors of hard use, year after year. A limited-edition variant of that proven workhorse, our Waxed Rugged Twill Original Briefcase has been heavily-waxed for unfailing water resistance and is available in a camouflage pattern that harkens back to vintage military uniforms.

Because it’s manufactured with the sturdiest materials and construction, we’ve had customers report logging over a million air-travel miles with their Original Briefcases. Our industrial-strength Rugged Twill is thick and strong, with exceptional resistance to abrasion and wear. It’s waxed, so your valuables stay dry. The leather handles and straps are cut, burnished and edge-dyed in our Seattle factory from Bridle Leather hides vegetable-tanned by one of the oldest tanneries in America. Each hide is slowly steeped in a special bark-tannin solution, with tallows and waxes “hot-stuffed” into it during the final stages. This eco-friendly tanning process transforms cowhide into durable, pliable leather suitable for horse tack and saddlery, as well as Filson briefcases. The heavy-gauge brass zipper is rustproof, virtually indestructible, and reinforced with Bridle Leather. All of this is stitched together with heavy-duty, cotton-wrapped polyester thread, to ensure a briefcase that will provide decades of unfailing service.

Every design detail of our special-edition Waxed Rugged Twill Original Briefcase was carefully considered–even the ones that aren’t obvious, such as the binding on the interior seams that prevents fraying, and the double-layer bottom for added protection and durability. While its trim design wasn’t intended for carrying large computers, the two interior dividers can accommodate tablets or smaller laptops. With slotted interior pockets for pens, tools and cards, keeping organized is a cinch. The Bridle Leather shoulder strap is removable and adjustable for a custom fit, and features a sliding shoulder pad to for comfort with heavier loads. Custom solid brass hardware is sand-cast and debossed exclusively for Filson, because every detail matters.

Do not wash or dry clean – brush or wipe clean with a damp rag. Rewax as needed to maintain maximum water resistance. To prevent the transfer of oils, we recommend avoiding prolonged contact between Filson oil finish goods and light-colored fabrics, especially in warm weather.
