    • HJC Adwatt Helmet SS20

  • HJC Adwatt Helmet

    You may have seen the HJC Adwatt Helmet during Victor Campenaerts' smashing of the World Hour Record. Now you can enjoy the same incredible aerodynamic performance and revel in the cool airflow as you attempt your own time trial records and speed around the banked boards of the Track. 

    It's Fast. And it's Cool. 

    Whether you ride the Adwatt helmet with the eye shield or without, you'll enjoy fantastic levels of aerodynamic efficiency. And not just that, knowing the intensity of riding fast, the HJC team ensured the helmet was going to offer outstanding levels of cooling airflow for such a speed-focused helmet. 

    In order to balance both smooth airflow and ventilation, the Adwatt benefits from HJC's Ventury Dynamics design. This makes use of pressure difference across the surface of the helmet to actively draw air through the helmet to keep you cool, all without forgoing raw aerodynamic performance. Every time you pull on the Adwatt you're giving yourself an advantage in pursuit of higher speeds and fast times. 

    Safety at Speed.

    While the Adwatt has been developed to be super-fast, you want to have the best level of protection too. Just like their road race helmets the Adwatt features a tough polycarbonate outer bonded to a shock-absorbing EPS foam liner. The polycarbonate outer adds structural integrity and strength while the foam inner provides energy dissipation and protection from the forces of crash impacts. The EPS foam is also reinforced by a skeletal frame integral to the core, increasing overall strength and holding the helmet intact during multiple impacts.

    From the speedy whir of tyres on a banked Track to the pursuit of fast times in a road Time Trial, the Adwatt ensures you're not being held back by your headwear.
