The fastest road helmet we’ve ever crafted,
performing in all riding positions.
To push aerodynamic performance beyond limits, we developed the Comete Ultimate: the fastest road helmet we’ve ever created, engineered to deliver measurable gains in every riding position.
Born in the wind tunnel and refined through advanced CFD simulations, it was tested against the top-10 performing helmets used in the World Tour using a rigorous testing protocol at 50 km/h, across two riding positions and 3 yaw angles (0°, 10°, 20°). The result is a helmet that consistently outperforms the competition. In aero position, it delivers up to 7.5 watts saved versus the closest competitor, and up to 15 watts on average across the test panel. On upright position, where riders spend most of their time, it saves 9 watts on average.
It integrates a new concept: AeroFlow disruptors. This aerodynamic innovation accelerates airflow at a critical point before separation. This key concept on its own saves up to 5 watts.
To balance speed with thermal efficiency, the CFD-optimized AirChannel ventilation system channels air through large front vents, deep internal channels, and rear exhausts, delivering active ventilation without compromising aerodynamic performance.
The Comete Ultimate also delivers pro-level comfort. The RS360 retention system ensures precise adjustment and a secure, stable fit at high speed, while the Mips® Air Node Pro system, combined with Coolmax padding, enhances moisture management and long-lasting comfort. Lightweight, adjustable straps sit naturally and integrate seamlessly with eyewear.
More than a helmet, the Comete Ultimate is a pure performance weapon, engineered to convert every watt into a decisive advantage.

The fastest road helmet,
both in aero and upright position
Born in the wind tunnel and refined through CFD, the Comete Ultimate outperforms the top 10 World Tour helmets.
It delivers an average of 9 watts saved in the upright position, where riders spend most of their time, and is even more dominant in the aero tuck, saving 7.5 watts over the closest competitor and 15 watts on average across the test panel.
It also features the AeroFlow disruptors. This key concept alone saves up to 5 watts by accelerating airflow right before it separates from the helmet.
Over a 50 km race, the COMETE ULTIMATE can give you up to a 11-second gain compared to the best competitor. (1)

Top-tier thermal comfort
with no compromise on performance
The CFD-optimized AirChannel system connects large front vents, deep internal channels, and efficient rear exhausts to maximize airflow through the helmet.
It delivers active ventilation without sacrificing aerodynamic performance.
Coolmax padding now featured on Mips Air Node PRO enhances moisture management and provides long-lasting thermal comfort.

Approved by the pros
"From the first ride you feel how well it cuts through the wind. The fit is dialed, sitting securely and safe. What impressed me the most is how it balances performance and comfort. Often, aero helmets sacrifice breathability, but this one manages to keep you cool during hard efforts.
Performance in gravel is getting more important each year with a healthy focus on aerodynamics. A fast aero helmet saves us some important watts to get us fresher into the final."

Mavic R&D team commitment
The development of the Comete Ultimate relied on an uncompromising aerodynamic testing protocol combining CFD simulations with real-life testing in Hepia Geneva Wind Tunnel.
The R&D team ran over 750 hours of CFD simulations, including 108 hours of optimization, to refine every surface and airflow interaction around the helmet. To validate these virtual results in real-world conditions, multiple helmet iterations, along with the top 10 World Tour were tested during 25 hours of wind tunnel sessions. Conducted in a controlled environment with stable atmospheric conditions, these tests precisely measured aerodynamic drag in watts at 50 km/h, across both upright and aero riding positions, and at yaw angles of 0°, 10°, and 20°.
This rigorous development process led to the fastest road helmet we’ve ever created.
Our best technologies
Through an iterative R&D process of 2D and 3D design, CFD simulations, and wind tunnel testing, the Mavic team fine-tuned every detail of the helmet to achieve optimal aerodynamic performance.
- AeroShape: Engineered for ultimate speed
Length, width, height, and thickness. Every dimension of the Comete Ultimate has been precisely engineered and optimized through extensive wind tunnel testing and CFD analysis.
All within the strict constraints of certified helmet protection standards, to achieve one goal: defining the most aerodynamic shape possible. This helmet is compliant with UCI regulations.
- AeroFlow disruptors: 5 watts gains
Developed through iterative wind tunnel testing, AeroFlow disruptors are designed to control airflow at a critical point, just before separation.
By accelerating the airflow and keeping it attached to the helmet surface for longer, they reduce the size of low-pressure zones behind the helmet, minimizing drag.
This key innovation alone delivers up to 5 watts.
- Mips® Air Node Pro: Advanced rotational impact protection
The latest Mips® Air Node Pro system is designed to reduce rotational forces in the event of an impact, helping to enhance rider safety.
Integrated seamlessly into the helmet, it now features Coolmax® padding for improved moisture management and long-lasting thermal comfort.
Dedicated sweat channels redirect moisture away from the forehead and eyes, so you can stay focused on the ride.
- AirChannel: Zero compromise on ventilation.
The CFD-optimized AirChannel system combines large front vents, deep internal channels, and efficient rear exhaust to maximize airflow through the helmet.
Engineered to enhance cooling, it delivers active ventilation without sacrificing aerodynamic performance.
- RS360 fit system: Precision & fit
The RS360 Fit System delivers precise adjustment and a secure, stable fit, even at high speed.
Its 360° retention belt wraps evenly around the head, adapting to every head shape for consistent comfort and support.
- Eyewear Garage: Stored. Not lost.
The Eyewear Garage provides a secure and convenient place to store your sunglasses when you’re not wearing them.
Whether during a climb or a break, your eyewear stays safely in place and always within reach.
