The Spyder Boys' Guard Jacket is a force field against winter weather so your little guy never has to slow down out there. With an Xt. L membrane, taped critical seams, and Spylon DWR coating, this jacket offers long lasting waterproof protection with breathable comfort. Polyester fabric and nylon taffeta lining combine to offer durability against the abuse of winter fun, and the removable hood gives him versatility during warmer shoulder seasons. And when he doesn't need to layer on sub zero days, the 3M Thinsulate insulation steps in to keep him warm and cozy without hindering his mobility.
