Giro Aries Spherical Bike Helmet

Spherical Technology is a ball-and-socket design that allows the helmet's outer liner to rotate around the inner liner during an impact. This helps redirect impact forces away from the brain more effectively than traditional slip-plane systems, providing a more comprehensive safety profile.

Yes, it is designed specifically for high-performance cooling. With 24 vents and a structural reinforcement arch that promotes airflow, it is one of the most breathable options in the Giro lineup.

The helmet uses Progressive Layering with two distinct densities of Nanobead EPS foam. The outer layer is designed to manage high-speed impacts, while the inner layer is optimized for lower-speed energy management, covering a wider spectrum of potential crash scenarios.

Yes, the Roc Loc 5+ Air fit system is designed for single-handed adjustments. You can easily tighten or loosen the tension while on the bike to accommodate changing conditions or comfort preferences.

The IONIC+ padding is treated to inhibit odor-causing bacteria, which helps keep the helmet fresher for longer. It also works in tandem with the internal channeling to wick moisture away from your brow during intense efforts.

While it is optimized for road cycling aerodynamics, the Aries is perfectly suitable for gravel riding. Its lightweight construction and high ventilation make it an excellent choice for long, endurance-focused rides on any drop-bar bike.
