The Reigning Champ Warm-Up Downfill Jacket keeps our muscles warm as we stretch before laps around the local track and for the drive to our local gym. The lightweight goose down keeps warmth close to our body for maximum comfort on chilly days, and the DWR treatment ensures the down stays lofty on misty days. The adjustable hood and hem ensure we stay warm and comfortable while the wind blows, and the entire jacket easily packs down into its own pocket, so we can bring it along for every workout.
