Aero Time Trial Helmet with Superior Ventilation

Description

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.

Features
  • Aerodynamic Profile: Sleek contours and wind tunnel-tested design minimize drag for higher speed with less effort.
  • Optimized Airflow: Advanced air channel system circulates cool air through the helmet, dissipating heat for lasting comfort.
  • Bernoulli-Based Ventilation: Ventury Dynamics technology extracts heat via pressure differences for efficient cooling while riding.
  • Lightweight Comfort: Feather light construction reduces strain during long triathlons and time trials.
  • Enhanced Structural Strength: In-Mold construction bonds EPS and polycarbonate for improved durability and protection.

Technologies

  • Wind Tunnel Tested: Precision-tested in HJC’s own lab to measure aerodynamics, ventilation and noise in real-world conditions.
  • Aerodynamic Design: Developed from MotoGP helmet expertise for optimal balance between speed and ventilation.
  • Advanced Air Channel System: Increases internal airflow to keep the rider’s head cool and heat-free.
  • Ventury Dynamics: Applies Bernoulli’s principle for pressure-based heat extraction and airflow optimization.
  • In-Mold Construction: Fuses EPS and polycarbonate for compact reinforcement and a perfect finish.
  • Feather Light: Engineered with optimized density and materials for the lightest possible weight.
