Little kids demand lots of warmth. That's why the boys' Burton Minishred game day jacket provides low-profile and potent Thermacore that strategically insulates the body, sleeves, and hood for the ultimate balance of warmth and wiggle-room. Room-to-grow sleeves extend for a fit that keeps up, while the hood snaps off for snug comfort when snoozing in the car seat. Little details like the Cuff-Link thumb loops keep junior covered when high-fiving after an awesome adventure. Fabric Type: Membrane:100% Polyurethane/Shell:100% Polyester/Taffeta - 100% Nylon/Tricot: 100% Polyester.
