Designed with CFD and VR, proven in the wind tunnel with 2x Tour de France winner Jonas Vingegaard, the Aerohead II Mips; is our most aerodynamic time trial helmet ever. With the protection of Mips; Air Node, a lightweight and ventilated solution for rotational energy management CE and CPSC safety standards are met and exceeded. Visibility is optimized with a magnetically attached oversized eye shield that is positioned away from the rider's face, allowing air to flow over the brow and beneath the Roc Loc; 5 Air fit system. Each Aerohead II comes with two eye shields (Clear and Vivid; Smoke) and a padded carrying pod. Engineered speed — the Aerohead II is your advantage.

Hardshell with In-Mold Hardbody™ Lower Wrap
Durable two-piece shell construction fuses a tough outer shell with a polycarbonate lower wrap—delivering strength without excess weight.
MIPS® Air Node Technology
A low-friction layer laminated to the comfort padding, designed to reduce rotational energy during angled impacts. Lightweight, breathable, and engineered for enhanced protection.
Roc Loc® 5 Air Fit System
Micro-adjustable dial offers independent tuning of fit and vertical positioning, while optimizing airflow and helmet stability for all-day comfort.
Super Fit™ Engineering
Based on over 25 years of fit data and handcrafted design, Giro’s sizing molds match real human head shapes—ensuring a secure, custom-like fit across four adult sizes.
Wind Tunnel™ Ventilation
Proprietary system channels cool air in and pushes hot air out through active vents and internal exhaust paths. The result: noticeable cooling on every ride.
Ionic+® Padding
Infused with pure silver for natural, permanent odor control—keeping your helmet fresh, ride after ride.
Deep Internal Channeling
Aggressively sculpted liner works in tandem with Wind Tunnel vents to guide airflow efficiently through the helmet, enhancing cooling and comfort.
