Ultra-light, comfortable helmet offering optimal ventilation. Unique shape enhances aerodynamics while providing optimal ventilation. Developed in the HJC wind tunnel. Designed for intense physical performance, even in hot weather. This helmet is used by the professionals of the Lotto Soudal UCI team. The helmet weighs 200g and has 16 ventilation holes with surprising aerodynamics. It is equipped with the classic features of a goggle hole, adjustable occipital support or antibacterial padding. Technology: SELFIT - unique self-adjusting tightening system, offers 5 default adjustment positions for different head shapes and circumferences. Coolpath - a new technology replacing the internal padding on the top of the head, allowing optimal air circulation around the head for increased comfort during racing. Ventury Dynamics - a technical adaptation of Bernoulli's physical principle is applied to HJC's improved aerodynamic models to achieve the best possible ventilation. Thanks to pressure differentials, cool air from the front is exhausted through the rear opening for vital heat dissipation, providing the rider with optimum ventilation and perfect flow during the race.
