HJC Adwatt 1.5 Aero Road Cycling Helmet - Matte Black

The ADWATT 1.5 is the perfect compromise between aerodynamics, ventilation, and comfort for particularly long riding sessions. Based on the ADWATT's advanced technology, it was designed through enhanced wind tunnel testing to improve its drag force performance on the road, while keeping your head cool, making the ADWATT 1.5 your perfect triathlon helmet.

Wind Tunnel Tested HJC helmets are tested in the laboratory as well as in "real life" to meet the highest quality standards. HJC is one of the very few helmet companies equipped with its own state-of-the-art wind tunnel laboratory to test aerodynamics, ventilation, noise, and more. The HJC wind tunnel test lab measures the air forces in a variety of riding conditions to improve helmet performance. In order to achieve maximum ventilation, a technical adaptation of Bernoulli's principle is applied to HJC's aerodynamically enhanced models. In motion, the rate of surface flow generally increases as it progresses towards the rear of the helmet. Through pressure differences, cool air from the frontal intake is extracted through the rear vent for internal heat dissipation, giving the cyclist optimum ventilation and perfect air flow while riding.
