Patagonia Boys’ Lightweight Synchilla Snap-T Fleece Pullover. Your first Snap-T® is practically a rite of passage; from there, you move onto snowshoeing among moose and then catching air at Pete’s Hill. Made from lightweight, warm double-faced, all-recycled polyester fleece, Patagonia’s boys’ pullover features classic Snap-T styling, including a stand-up collar, a 4-snap nylon placket, a nylon-flapped pocket at the left chest and tried-and-true Y-Joint sleeves for overhead mobility. Spandex trim on the cuffs and hem keeps in heat. Hand-me-down ID label. Hip length.
