Amazon.com Product Description:
The perfect choice for biking, skating, or any other sport that requires protective headgear, the Razor Aggressive helmet increases your child's safety with its multi-impact liner, extended rear coverage, and ergonomic, classically-designed shape. It fits youth head sizes 21.5 to 23 inches (ages 5 and older), and is ideal for street use or half pipe action. Eleven vents will keep active skaters' and bikers' heads cool at all times and the side release buckles make it a breeze to adjust and fasten the chin strap.

Rating : - Nice hat!
I was hesitant about buying this because my son will just be 4 when he is able to use it, but it turns out that it is not too big. It is a little oversized, but I'm sure that not only will he grow into it quickly, but it will be a helmet that he can wear for a long time. The velcro pads inside the helmet (for adjusting the fit-pads - if you need them) were not glued on very well, but your own bottle of super glue can quickly fix that.
