The helmet is a very important piece of safety equipment for any shredder. Junior shredders need one even more due to their tendency to eat pavement. The Triple 8 Brainsaver Little Tricky Jr. Skateboard Helmet is designed for those kids who take a beating and keep on skating. Plus it has some adjustable straps so as the mini grows, the helmet's use can be extended. One size fits most - Youth ages 6-11 (Each helmet comes standard with an extra set of fit pads to better customize fit) - fits size 49-52 cm or 19.3-20.5 in.
