kids demand lots of warmth. that's why the boys' burton game day jacket provides low-profile and potent thermacoreâ„¢ that strategically insulates the body, sleeves, and hood for the ultimate balance of warmth and wiggle-room. room-to-growâ„¢ 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.
