This helmet is cool looking, solid color, has air holes all along the top for breathing and most importantly is certified all the way across the board. I don;t know if a lot of parents realize that only certain helmets meet safety guidelines for actual protection.
The measurement for the small/medium is 21.5"-22.75". make sure you measure because you really want the correct fit. That is how it protects your head best, only when it fits properly.
