Goldwin's Crystallite down jacket combines a nylon shell with a quilted structure for lightweight warmth. The jacket features a 80% down, 20% feather fill, a full-length centre zip, an adjustable drawcord hood, and deep side pockets. The nylon exterior and lining provide weather resistance, while the boxy quilted panels offer a contemporary silhouette. Wear layered under a shell jacket in cold weather or as a standalone mid-layer piece.
