Woom Kids Helmet blue 46-50cm | The shapes and proportions of children's and adult heads are different. Therefore, we have tailored the Kids Helmet to meet the needs of children! This means a specially designed helmet shell for the protection of the forehead, temples, and back of the head, an easy-to-use magnetic closure, optimal ventilation, and fine size adjustment through a rotary switch. A unique safety feature is the flexible visor, which serves as additional impact protection!
