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!

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.

Internal Reinforcement Structure

The helmets are reinforced with an internal frame integrated into the EPS, the skeletal frame not only holds the helmet in one piece, but also makes it stronger and more resistant to protect your head in the event of a collision.
