The KUHL Women's Spyfire Jacket delivers low-bulk warmth with thoughtful design for high-output activity. Strategically placed 800-fill RDS-certified goose down insulation keeps your core warm, while underarm knit gussets release excess heat for sustained comfort. Reinforced overlays and a softshell yoke, collar, and zipper garages enhance durability without adding weight. The articulated 4-fabric design ensures a flattering fit that moves with your body, and reflective trims provide visibility when conditions are low. Functional pockets and elastic cuff bindings make this jacket as practical as it is stylish, perfect for winter adventures or urban layering.
