The Toddler Patagonia Capilene Silkweight Hoody is made from stretchy recycled polyester and spandex jersey with 40+ UPF sun protection. The smooth jersey fabric is comfortable against the skin and slides easily under layers, with flat-seam construction throughout that prevents chafing. The grown-on, three-panel hood offers a great fit and extra coverage around the neck while set-in sleeves with underarm gussets aid mobility.
