Adwatt TT Helmet | HJC | Aerodynamic Design

Product Description

As the fastest aerodynamic helmet ever tested in a wind tunnel, the Adwatt is in a league of its own. In close collaboration with European TT champion Victor Campenaerts and HJC experts, the helmet was tested and developed in a wind tunnel in Belgium until all involved were more than satisfied with the results. Thanks to the unique design of the Adwatt, the helmet provides fantastic aerodynamic measurement values that are nearly identical with and without a visor. At the same time, the Venturi Dynamics system ensures maximum ventilation. - Tested and proven in a wind tunnel - Removable visor - In-Mold construction - Adjustable fitting system - Two ventilation channels - Weight: 340g with visor / 280g without visor
