HJC ADWATT 1.5 AERO HELMET (WHITE)

The Adwatt 1.5 is the perfect compromise between aerodynamic, 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.

This helmet has 2 vents and weights about 260 g without its visor, or 320 g 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 spare pads, wash bag and a premium case to protect the helmet and its shield when you travel.

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.

                                                                                                                                                        

Aerodynamic Design
Coming from MotoGP race-helmet design experience, HJC designers and engineers have become experts in aerodynamics and wind ventilated helmets. Aero helmets, as the word implies, are more aerodynamic than the conventional racing bike helmet, but with compromised ventilation performance. With HJC Helmets, this compromise is very much reduced. HJC offers probably the best ventilated semi-aero helmet on the market…. Save Watts with HJC Helmets!

                                                                                                                                                       

Ventury Dynamics
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.

                                                                                                                                                    


In-Mold Construction
In-mold is a method consisting in bonding the EPS together with the outer polycarbonate shell for greater structural strength. This improves the rider’s protection by providing a compact reinforcement and gives the product a perfect finish.

                                                                                                                                                  

Advanced Air Channel System
A certain amount of air passes through the front air-intake port, then circulates inside the helmet and finally exits through the exhaust port. The internal airflow is then increased to cool the head and evacuate the heat.

                                                                                                                                                

Mirror shield
Aero Time Trial Helmets are equipped with a shield to improve the riders’ comfort and visibility, HJC’s aero helmets are engineered in order to have the same aerodynamic performances with and without a shield.
                                                                                                                                               

X-static fabric
X-STATIC® is made by permanently bonding 99.9% metallic silver to the surface of a fiber. It is not a nanotechnology, or a complex chemical formula; X-Static is natural silver. The permanent performance of X-STATIC® keeps apparel smelling fresher for longer, even after multiple wear cycles between washings.

                                                                                                                                             


Adjustable wide divider
The wide divider has an angle of 55º to prevent from twisting of the chin strap and ear interference and provides confortable fit.


                                                                                                                                           


Feather light
HJC bicycle helmets are designed and engineered through precise measures to have the lightest weight possible. Density, placement, shapes and materials all play a part in weight optimization.

                                                                                                                                          

About HJC

HJC has been developing and manufacturing helmets since 1971.

Highly praised in the field of motorcycle helmets, HJC is recognized for its long history of helmet production involving advanced material construction, strength and lightweight performance. With over 50 years in commitment to excellence and advancement in helmet technology, HJC has mastered the art of making helmets to premium standards. The brand has distribution in over 80 different countries worldwide, with various helmet categories representing 20% of the European motorcycle helmet market.

The tests in HJC’s wind tunnel laboratory and the direct feedback of top Moto GP riders, have enabled HJC to improve the fitting and aerodynamics of its helmets. The applied Venturi Dynamics considerably reduce the drag force at high speed and balance the air resistance force with exhaust ventilation.

Being the #1 helmet manufacturer in the world for years, HJC has a legacy to nurture. HJC invests heavily in design and development in a variety of categories, working hand in hand with global partners and advanced technologies.HJC plans to develop and manufacture next level cycle helmets, with strategic choices made in the creation and introduction of new construction methods.
