Review on 🧢 EMPIRELION Thermal Helmet Liner for Kids - Lightweight Beanie Covering Ears, Thin Skull Caps for Boys & Girls, Ideal for Running by Brandon Rogers

Great for my 3 year old. We live in Colorado and he enjoys riding his bike and scooter, even (or especially!) on snow and ice. We tried ski helmet style headphones but he said they sounded fun. It's very thin, but at least keeps you a little warmer. We really had to increase the size of the helmet when he wears that, otherwise the helmet would sit too high.
