This helmet is the ideal bike helmet for children with a head circumference of 48-55 cm. With its outstanding features, it not only guarantees optimum protection, but also a high level of comfort. The helmet impresses with its optimum fit and form-fit, which is achieved thanks to the padded plastic ring. This can be adjusted with one hand using the practical twist adjustment system to ensure a perfect fit. Your child can easily adjust the helmet themselves. The 17 ventilation holes ensure optimum ventilation and keep the head pleasantly cool even on warm days. There is also an integrated insect screen to keep pesky visitors at bay. For additional safety, the helmet has a removable light module at the back. With its three modes (continuous light, flashing light, off), it ensures optimum visibility in road traffic. The 360-degree visibility is further enhanced by the four reflector stickers so that your child is easily recognisable even in poor light conditions.
