Bike helmet size guide:

Designed for everyday mobility, this Italian-made bicycle helmet with a visor focuses on the essentials: protection, lightness, and clear vision. Its In-Mold construction offers a very lightweight structure, ideal for riding in the city or on greenways without the feeling of a heavy helmet. The category 0 (sun protection 0) Clear visor provides transparent protection: it cuts the wind, limits debris (dust, insects), and improves visual comfort, all while maintaining an ultra-natural look. The result: a feeling of freedom with the peace of mind of an integrated visor.
