"Wind, snow, and cold make it hard to see. Most kids do better with goggles than sunglasses. All ski helmets have some sort of clip on the back side to hold the goggle strap securely in place. It's easier for kids to put the goggles on the helmet first, and then put the helmet on their head. If the goggles are secure they should stay on the helmet all day. Most important, don't sit on them!"
