When the acorns drop and the young ones head out to collect them, the Kids’ Retro-X® Vest is a good call. Not only is it warm and windproof, it also won’t hinder the throwing motion once the chucking begins. The fluffy, quarter-inch pile, made of durable, 100% polyester fleece (70% recycled) is lined with windproof polyester. SUPPLEX® nylon contrast reinforces the fleece-lined collar, front-zip binding and double-layer, patch handwarmer pockets. Hand-me-down ID label.
