I bought this pack to my three old years son but the helmet is some big to him and I cannot adjust it to his size. On the contrary, the pads are a little small for him.
Anyway, he use them to ride his bicycle. 3 stars

The sizing on this item is off. It fit my granddaughter, who is 2yrs, 9 mo. but didn't even come close to the intended 4 yr, 8 month old boy.....way small. I didn't see a process for purchasing according to head diameter, so the item was useless for it's intended recipient. 2 stars

My 5yr old grandson thinks he is very cool now because he has the Spiderman bike and the helmet and pads. 5 stars

I brought this product as a Christmas present,the Little Man loved it!!! He was falling on the floor and bumping his head and we all knew he was safe!!! I think he like the helmet better than the Spiderman Scooter. Thanks for a great product and wonderful fit. 5 stars
