Great helmet. My preschooler had a bad fall off her balance bike and got a split lip while wearing a regular helmet. I've been unsure about allowing her back on, and this helmet has eased my worries significantly. It's sits firmly on her head and she says it's comfortable. So glad I was able to find this in a smaller size. Highly recommend if you have a daring 3-5year old like mine, that think they can pull 8year old stunts :)
