The superdurable windproof and water-resistant Patagonia Boys Down Sweater Vest provides lightweight, reliable core warmth. The vest's high tear-strength, mini-ripstop shell fabric, and the polyester taffeta lining are treated with a DWR (durable water-repellent) finish. Compressible Recycled Down (600-fill-power duck and goose down reclaimed from down products) provides unrelenting warmth. Vest details include a full-length zipper with garage and wind flap; handwarmer pockets with reflective webbing pulls; comfortable quilt-through construction; internal drawcord at the hem and a hand-me-down ID label.
