HJC Adwatt 1.5 Aero Helmet

The HJC Adwatt 1.5 Aero Helmet strikes the perfect balance between aerodynamics, ventilation and comfort, making it ideal for long-distance triathlons and time trials. Developed with advanced design principles, it delivers reduced drag while keeping your head cool over extended rides.

Wind Tunnel Tested for Real Performance: Every Adwatt 1.5 undergoes rigorous testing both in the lab and in real-world conditions. HJC is among the few helmet manufacturers with its own state-of-the-art wind tunnel facility, allowing precise measurement of aerodynamics, ventilation and noise in varied riding scenarios.

Aerodynamic Design Backed by Science: Enhanced through wind tunnel development, the Adwatt 1.5 minimizes drag force, helping you maintain higher speeds with less effort. Its sleek profile and strategically shaped contours are fine-tuned for maximum efficiency in racing positions.

Advanced Ventilation Using Bernoulli’s Principle: To achieve optimal airflow, the helmet applies a technical adaptation of Bernoulli’s principle. Cool air enters through the front intake, circulates through the interior and exits via the rear vents—actively dissipating heat for consistent comfort.

With its blend of aerodynamic efficiency, cooling performance and long-wear comfort, the HJC Adwatt 1.5 is the helmet of choice for serious triathletes and time trial riders aiming to push their limits without compromise.
