The HJC Adwatt was designed through enhanced wind tunnel testing. Designed to improve its drag force performance on the track the HJC Adwatt is a fast helmett. Using the HJC ADWATT time trial helmet, Victor Campenaerts and the LOTTO SOUDAL UCI World tour team beat the UCI HOUR RECORD in April 2019. The HJC Adwatt time trial and triathlon helmet was developed to be aerodynamically optimised with and without a visor. The HJC Adwatt has been tested multiple times by ourselves. The Adwatt always tests well against other time trial helmets and triathlon helmets.

- 320g (±10)incl. visor
This helmet has 2 vents and weights about 260g without its visor, or 320g with its visor. HJC successfully took up the challenge of developing an Aero helmet which is efficient both with and without a visor, creating a helmet that is fast and extra ventilated at the same time.
This helmet comes with a premium case to protect the helmet and its shield when you travel
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.
