Great protection when the kids are in action - and the cool look of a pro on dirt bikes. Uvex hlmt 4 protects them on dirt and normal bikes, skateboards, inline skates and scooters. This hard-shell children's helmet offers a stylish, high-gloss design that is impact-resistant on the outside, shock-absorbing on the inside and adjustable to fit your child's head thanks to the IAS system. 10 large ventilation holes reliably protect against heat build-up. Children can easily open and close the Monomatic with one hand. An optional plug-in LED provides even greater visibility and safety in the evening.
