The bomber jacket is a timeless military-inspired garment. With this release from Filson, it receives a cold weather-ready makeover. The torso is made from 8-oz. water-resistant oil finish Cover Cloth, while the shoulders and sleeves have waxed 11-oz. Shelter Cloth shells for added durability. Ethically sourced goose down insulation provides outstanding warmth, helped along by wool-blend ribbed cuffs and hem to help block out the wind and 100% wool lining for the oil finish Shelter Cloth patch pockets.
