A rear dial-fit system and adjustable nylon straps ensure a snug, secure fit for head circumferences of 54–58 cm. Certified to CE EN 1078, this unisex helmet is ready for cycling, mountain biking, scooter rides, and skateboarding.

Good to know

The helmet weighs approximately 450 grams, balancing protection and comfort for younger necks. The detachable visor shields eyes from sun and trail debris, while the quick-release buckle allows kids to take the helmet off without help. Always replace any helmet after a significant impact, even if no damage is visible. For best fit, measure the child's head circumference just above the eyebrows and ears before ordering.
