The Down Bomber Jacket pairs our signature waxed cottons with nature's warmest insulation for heavy-duty warmth in a hip-length jacket. The torso is constructed from 8-oz. water-resistant oil finish Cover Cloth, with waxed 11-oz. Shelter Cloth for the shoulders and sleeves for increased durability and weather protection. The patch pockets are made from oil finish Shelter Cloth and lined with 100% wool for warmth. The classic bomber design features sturdy wool-blend ribbed cuffs and hem to keep warmth in and seal out cold wind. The 650-fill-power down insulation is responsibly sourced, certified under the Responsible Down Standard, and can be tracked back to the original farms to ensure ethical practices are followed.
