HJC Adwatt Matt Black L

The Adwatt was designed through enhanced wind tunnel testing to improve its drag force performance on the track. 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. HJC have successfully developed 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.Key Features• Wind tunnel tested - HJC has a state-of-the-art wind tunnel laboratory to test aerodynamics, ventilation, noise and more• Aerodynamic design - HJC are experts in aerodynamics and wind ventilated helmets• 2 vents• Venturi dynamics - 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• In-mold construction - EPS is bonded together with the outer polycarbonate shellfor greater structural strength• Advanced Air Channel System - increased cooling airflow to head and evacuation of heat• Mirror shield - to improve the riders' comfort and visibility• X-static fabric - keeps apparels smelling fresher for longer, even aftermultiple wear cycles between washings• Adjustable wide divider• Feather light - designed and engineered through precise measures to have the lightestweight possible• 260g (±10) – helmet only• 320g (±10) – incl. shield• Includes: premium case to protect the helmet when not in useSizes• Small: 51-56cm• Medium: 55-59cm• Large: 58-63cm
