HJC ADWATT 1.5 Matte Black MT BLACK Bicycle Helmet.

The Adwatt helmet is the perfect compromise between aerodynamics, ventilation and comfort. It was created on the basis of the HJC Adwatt helmet and its aerodynamic properties were improved even more, but this time the focus was on comfort, bearing in mind many hours of competition over the longest triathlon distances, making it not only an accomplished time trial helmet, but also a triathlon helmet.

Fit and comfort are the most important features of HJC helmets. The technical department has patented the following revolutionary features to improve comfort while riding:

AERODYNAMICS

HJC designers and engineers became experts in helmet aerodynamics and ventilation when designing racing helmets for MotoGP. Commercially available aero helmets, as the name suggests, are more aerodynamic than classic bike helmets. Most often, however, at the expense of poorer ventilation.With HJC helmets, there is no question of compromise. HJC offers arguably the best ventilated semi-aero helmet on the market.

ADVANCED VENTILATION SYSTEM

Bernoulli's law was used to achieve maximum ventilation. Air flows through channels whose cross-sectional area increases causing a reduction in static pressure at the inlets to the channels. This results in faster airflow over the head and increased extraction of excess heat and moisture. The result is optimal ventilation of the head while riding.

Technologies used:

• Wind tunnel tested

• Magnetically attached glass

• X-STATIC - outer surface of the insoles coated with silver ions so they stay
  fresh for a longer time

• Aerodynamic shape

• Advanced ventilation channel system

• Venturi Dynamics - improved ventilation and reduced drag

• In-mold construction

• Internal stiffening system

• Low weight

Technical data:

• Weight approximately 260g (±10g)

• Weight of the helmet with glass 260g (±10g)

• 4 air vents

• Adjustable occipital clamp

• Antibacterial inserts

• Available in three sizes (S - 51-56cm, M - 55-59cm and L - 58-63cm)

Kit contents:

• HJC ADWATT 1.5 bicycle helmet in black color.
