Giro Helios Spherical Road Bike Helmet

The Giro Helios Spherical cycling helmet offers protection as well as ventilation for long rides on regular and gravel roads. It focuses on a precise fit and constant airflow to keep your head cool. The lightweight design and smart distribution of impact energy ensure both comfort and safety.

Construction and protection
The helmet uses Spherical Technology with MIPS and a ball-and-socket design that allows the outer shell to move around the inner shell, which helps to reduce rotational forces in the event of a fall. The Progressive Layering of the Nanobead EPS foam contributes to broad impact absorption. The full lower hardbody coverage reinforces the underside of the helmet and the in-mold construction firmly connects the layers. The result is a protective helmet that is still lightweight and offers a consistent fit.

Comfort and finishes
The Roc Loc 5 Air system allows for micro-adjustments to keep the helmet comfortably and securely in place during movement. The 24 Wind Tunnel vents with deep internal channels provide constant air circulation and cooling. The Ionic+ anti-microbial padding absorbs moisture and contributes to hygiene. Reflective decals increase your visibility in low-light conditions. The combination of all these details makes the helmet comfortable and functional in various conditions.
