A child's bike helmet needs to fit properly and feel comfortable. And that means it needs to be carefully designed to match the exact shape of kids' heads as they grow. We studied thousands of scans of children's heads when we were designing our READY Kids' Helmet. That's how we ended up with a helmet that fits and protects perfectly at every stage of a child's development - without slipping, wobbling, pinching, or digging in. Plus, we added plenty of ingenious details to keep your child safe and make it easy for them to put their own helmet on and take it off again.
