What Our Gearhead® Experts Are Saying: "My kid wears the Macon 2. 0 DVRT all winter—on the hill and even on cold bike rides. It fits snug, stays comfy with the winter liner, and gives us peace of mind with Bern’s dependable build. The dial adjustment makes it easy to fine-tune as they grow, and it’s great not having to buy a new helmet for every season."We want our young riders to feel confident, warm, and well-protected when they hit the slopes or cruise snowy trails—and the Bern Macon 2. 0 DVRT Winter Helmet is built to do just that. Bern’s commitment to safe, stylish helmets shines in this youth-specific design, which keeps things simple, secure, and fun all winter long. With a lightweight ABS shell and Bern’s DVRT (Directional Venting) system, this helmet balances airflow with coverage to prevent overheating without letting in the cold. The winter knit liner wraps little heads in warmth, and an easy-to-use dial fit system keeps the helmet snug and secure. Bonus points: it works with audio chips so they can bring their favorite music along for the ride.
