Giro Helios Spherical Helmet

Giro design, and high-performance innovation for core road cyclists, gravel enthusiasts, and adventure riders.

Advanced Performance for the Adventurous

At the core of the Helios's design is Spherical Technology, a ball-and-socket system powered by Mips® — the market-leading brain protection technology designed to reduce rotational forces during impacts. This innovative design allows the outer liner to rotate around the inner liner, while Progressive Layering enhances protection by managing impact energy more efficiently.

Beyond superior safety, the Helios delivers outstanding comfort and ventilation. With 15 Wind Tunnel vents and the Roc Loc 5 Air fit system, airflow is maximized to keep you cool on long rides. Plush, antimicrobial XT2 padding provides excellent sweat absorption and lasting freshness. Whether you're on the road or hitting the gravel, the Helios is built for performance and protection.
