Giro Aerohead MIPS Helmet
- MIPS® Brain Protection System
- Wrap-around ZEISS® eye shield with magnetic anchor
- Roc Loc® 5 Air fit system
The Giro Aerohead MIPS Helmet is a high-performance aero helmet built for time trials and triathlon racing, combining advanced aerodynamics, cooling efficiency, and impact protection in a single system. Designed in the wind tunnel and proven at the Tour de France and Ironman World Championships, it delivers measurable speed gains without sacrificing comfort or airflow. The integrated MIPS® protection system works alongside a lightweight aerodynamic shell and wrap-around ZEISS® eye shield to improve safety, visibility, and efficiency during sustained high-speed efforts.
Key Features and Benefits:
- Aerodynamic wind-tunnel-tested profile: The helmet shape was refined through wind-tunnel development to reduce aerodynamic drag at race speeds. Lower drag helps conserve rider energy over long efforts, allowing you to maintain speed more efficiently and sustain performance across full race distances.
- Integrated MIPS® Brain Protection System: A low-friction layer inside the helmet is designed to redirect rotational forces during certain impacts. This reduces energy transfer to the head, helping improve protection outcomes while maintaining a lightweight and race-ready structure.
- Wrap-around ZEISS® eye shield with magnetic anchor: The optical shield provides wide, uninterrupted vision with high clarity and reduced distortion. The magnetic attachment secures the shield firmly while allowing quick removal or flip-up storage, supporting smoother transitions and consistent visibility in changing conditions.
- Wind Tunnelâ„¢ ventilation with internal channelling: Active vents and internal airflow channels move cool air across the head while pushing heat out. This regulates temperature during hard efforts, helping maintain focus and comfort when effort levels and ambient heat increase.
- Roc Loc® 5 Air fit system: A micro-adjustable dial enables precise tuning of fit tension and vertical positioning. Improved stability keeps the helmet secure while enhancing airflow around the scalp, resulting in long-duration comfort without pressure hotspots.
- Hardshell with In-Mould Hardbodyâ„¢ lower wrap construction: A durable outer shell fused to a polycarbonate lower wrap strengthens the helmet while keeping weight low. This increases durability and structural integrity, ensuring consistent protection without compromising aerodynamic performance.
Aerodynamic efficiency matters most when every watt counts, and this helmet focuses on reducing resistance while maintaining cooling and stability over long efforts. The streamlined shell works with controlled airflow to manage heat build-up, while the ZEISS® shield maintains clear forward vision in aggressive riding positions. Integrated MIPS® protection and precision fit adjustment support confidence during high-speed racing, allowing consistent output without distraction from discomfort or instability.
The Giro Aerohead MIPS Helmet brings together proven race performance, reliable protection, and practical usability for competitive riding. Its balance of speed, cooling, and fit makes it a dependable choice when performance gains come from refined equipment choices.
