The Giro Aries Spherical is a premium road cycling helmet designed for riders who demand exceptional ventilation, low weight and advanced protection without compromising comfort. Built for racing, climbing and long days in the saddle, the Aries combines Giro's most sophisticated helmet technologies in a sleek, lightweight package.

At the heart of the Aries is Spherical Technology powered by Mips, using a unique ball-and-socket construction that allows the outer liner to rotate independently around the inner liner during certain impacts. This system is designed to help manage rotational forces while maintaining excellent ventilation and comfort.

Giro's Progressive Layering construction uses dual-density EPS foam to provide more comprehensive energy management across different types of impacts, while the AURA II Reinforcing Arch adds structural support and allows for large ventilation openings without compromising the helmet's integrity.

Cooling is one of the Aries' standout features. Large Wind Tunnel vents work together with deep internal channeling to move fresh air over the head while pushing warm air out, making it an excellent choice for hot-weather riding, climbing and high-intensity efforts.

The Roc Loc 5+ Air fit system provides precise adjustment while suspending the helmet slightly above the head to further improve airflow. Giro's DryCore sweat management system helps redirect moisture away from the rider's forehead, while Ionic+ padding provides lasting comfort and odour resistance.

Integrated eyewear docking ports provide a secure place to store sunglasses when they are not being worn, while full lower hardbody coverage improves durability and gives the Aries its refined, premium finish.
