Aries Spherical Mips Helmet

What Our Gearhead® Experts Are Saying:

"This helmet sets the bar for comfort and ventilation. The balance of low weight, airflow, and advanced impact protection makes it ideal for performance-focused road riding."

The Aries Spherical Helmet represents Giro’s most advanced approach to road helmet design, blending minimal weight with industry-leading protection and cooling. At the core is Spherical Technology powered by Mips, a ball-and-socket design that allows the outer liner to rotate independently around the inner liner during certain impacts, helping redirect rotational energy away from the brain. Progressive Layering further refines protection by using dual-density EPS foam to better manage both high- and low-speed impacts.

Cooling performance is driven by Giro’s Wind Tunnel ventilation system, combining 21 oversized vents with deep internal channeling that actively pulls fresh air across the scalp and exhausts heat efficiently. The Aura II Reinforcing Arch maintains structural integrity while allowing these massive vents to remain open and effective. Inside, DryCore sweat management uses an internal silicone bead to redirect moisture away from the eyes, while Ionic+ padding provides long-lasting odor control.

Designed for high-output road riding, the Aries Spherical Helmet also features eyewear docking ports for secure sunglass storage and the Roc Loc 5+ Air fit system, which suspends the helmet slightly off the head to enhance airflow while allowing precise adjustment. From long alpine climbs to aggressive race-day efforts, this helmet delivers state-of-the-art performance, protection, and comfort for riders who demand the best.
