Patagonia's Retro Vest provides kids with vital core insulation and has practical applications as well, such as freeing up arms to skip rocks, climb slabs, or set a personal best in the dirt-clod toss. The quarter-inch pile exterior is made from 75% recycled polyester fleece and is backed by a polyester mesh laminate for additional warmth and wicking. Features like contrast nylon Supplex stylishly reinforces the double-layer handwarmer pockets, front-zip binding, and a neck-friendly fleece-lined collar make this old favorite a sure hit for a new generation.
