HJC Adwatt 1.5 TT Helmet

Born in the wind tunnel, the HJC Adwatt 1.5 TT Helmet takes the renowned Adwatt platform and adds the ventilation necessary for longer events, allowing you to save key watts on your next Ironman or time trial. With a robust, in-mould construction, the Adwatt 1.5 ensures impressive protection in the event of a crash, and the removable Mirror Shield visor adds aero-optimised eye protection. 

Advanced air channels add vital cooling, ideal for hard efforts in warmer climates. Developed with Venturi Dynamics technology, the aerodynamic design allows the Adwatt 1.5 to be one of the fastest helmets available, allowing it to glide through the air on your way to personal bests and podium finishes.
