Filson makes some of the world's most rugged luggage and outdoor gear. Nearly indestructible, even. This duffle bag is made in Washington from their exclusive Rugged Twill, a tightly woven cotton twill that's lightly waxed to protect against abrasion and wet weather. It's trimmed in bridle leather with heavy-gauge, two-way brass zippers, and it's sized to meet maximum airline carry-on size restrictions.
