Giro Helios Spherical Helmet

The Giro Helios Spherical Helmet delivers advanced protection, exceptional ventilation, and premium comfort for riders tackling long road, gravel, and mixed-terrain rides. Engineered for high-performance cycling, it combines cutting-edge safety technology with a lightweight, well-ventilated design to keep you cool, comfortable, and protected during demanding efforts.

At the core of the helmet is Spherical Technology powered by Mips, featuring a ball-and-socket design that allows the outer liner to rotate independently around the inner liner during angled impacts. This helps redirect rotational forces while eliminating the need for traditional hard plastic slip planes against the head. Progressive Layering further enhances protection with dual-density EPS foam, designed to better manage both high- and low-speed impacts. With 15 Wind Tunnel vents and deep internal channeling, airflow is maximized to maintain consistent cooling throughout long rides.

Comfort is equally refined. The Roc Loc 5 Air fit system suspends the helmet slightly off the head to improve airflow while allowing precise, one-handed adjustments for fit and stability. Plush XT2 antimicrobial padding manages moisture and odor, ensuring lasting comfort across extended rides in warm conditions. Weighing just 270g (size medium), the Helios strikes an ideal balance between lightweight performance and all-day wearability.
