Helmet bought 50/55 size, blue ocean for a little boy of 3 1/2 years. The size is perfect. Very nice quality; Beautiful bright colors, Adam loves patterns. Easy adjustment thanks to its rear wheel. HELMET LIGHT, and that's important for our kids. The only gripe is the setting of the belt, we have the beautiful back up it is too long and can not keep it under the chin. We will therefore have to make something but it does not mean that we are going to buy a second offer. We do not regret this purchase, come packed in a handy box that we will keep for storage.
