GUC Ruched stitching on the sleeves, ribbed details and a utility pocket on the left arm give 1 side a traditional bomber look. Diamond quilting on the other side feels soft and warm as a liner and gives you a cozier look when worn reversed. Both sides feature snap hand pockets to keep your items stored securely. Garments with synthetic fill insulation provide a soft, durable layer of warmth to keep you comfortably on the go in cool conditions. 100% NYLON
