Protecting your loved ones is the first step in allowing your child to take the parks, gardens, and pavements by storm. So weve spent a lot of time perfecting the design of our helmet, to ensure its safe when scooting, biking, or skateboarding. And something your little one will want to be seen wearing! Built using impact-resistant and shock-absorbent materials for the outer shell. And cleverly placed EPS foam padding for added comfort. Designed with 11 cooling air vents, and breathable foam to help kids keep cool. Adjustable chin strap and sizing dial to provide a firm but comfortable fit and enjoy years of use.
