Propero 4 Helmet

The Propero 4 helmet is the ultimate balance of speed and cooling, integrating the aerodynamic leading edge of the S-Works Evade 3 with the superior ventilation of the S-Works Prevail 3. This helmet is four watts faster than the Prevail 3 and features Micro Channeling for a continuous, refreshing airflow, all while earning the highest 5-Star Virginia Tech® safety rating.

• Aero Performance: Incorporates the aerodynamic front-end design of the S-Works Evade 3, making it four watts (15 seconds over 40km) faster than the S-Works Prevail 3.
• Maximized Cooling: Features Micro Channeling (2mm offset channels) and large rear-end vents to create turbulence and maximize cooling airflow throughout the helmet.
• Top Safety Rating: Earned the highest 5-Star Virginia Tech® Helmet Rating, confirming its superior protection performance.
• MIPS Equipped: Features the Mips Evolve Solution, a low-friction layer designed to reduce rotational forces transmitted to the brain during angled impacts.
• Premium Fit: Utilizes the FS3 Fit System and Occipital Base Adjustment for personalized fit, fine-tuning the angle for glasses compatibility, and includes dedicated sunglass storage.
