The Original Briefcase.

The Original Briefcase by Filson combines rugged construction with a classic shoulder bag design and the features for a modern on-the-go lifestyle. It’s crafted with Rugged Twill, which is industrial-strength cotton that’s water-repellent, abrasion resistant, and bound with dry-finish Tin Cloth. The Original Briefcase contains 13-liters of storage, and its inner compartment has dividers for a laptop along with slotted and utility organizations pockets. It features a removable and adjustable Bridle Leather shoulder strap with a pad, allowing for shoulder hauling or cross-body carrying. The handle straps, tabs, and trim are also saddle-grade Bridle Leather. Filson custom cut the YKK solid brass zipper for the most precise closure fit. They also outfitted this bag with a storm flap for additional security and weather protection.
