For brisk walks, fast commutes and outings that start cool and heat up, the Jayden Hybrid Jacket combines warmth with movement. Recycled nylon taffeta holds the 700 fill power duck down, stretch polyester honeycomb knit moves with the body, and underarm ventilation lets heat out once the effort builds. A water-repellent treatment and windproof fabric cover the mild, breezy parts of the day.
