This classic field bag is just the right size to carry your adventure essentials – say, notebook, binoculars and a flask of hot coffee, with a couple of useful extra pockets to take a wallet, sunglasses and notepad too. Made from water-repellent, abrasion-resistant rugged twill for durability and weather resistance, it’s built for the long haul. Rugged twill is Filson’s most hard-wearing luggage fabric – a tightly-woven, industrial-strength cotton that is lightly waxed for added protection from scuffs, scrapes and wet weather. Other details add the hallmarks of quality for which the brand is known – everything from the reinforced base and bound seams to a sturdy double buckle closure storm flap and an adjustable, removable shoulder strap made from saddle-grade bridle leather
