The ATARA benefits from all of the technical development of HJC’s high-end models such as the IBEX 2.0 and Furion 2.0. Aerodynamic and comfortable, the ATARA is your perfect entry into the world of HJC, an everyday helmet with a perfect fit. It is light in weight, easy to adjust to your head size and makes no compromise on security.

	SELFIT ™ SELFIT is an automatic self-adjusting fitting system which is a revolutionary technology in bicycle helmet fitting.  Once the helmet fit is set for your head it doesn’t require further adjustment, even when your head is moving during the ride. The SELFIT system automatically adjusts the gap and provides consistent fitting and comfort of your head.
	COOLPATH™ COOLPATH is a new technology replacing the inner padding, allowing the cool air to flow around your head and improving your comfort during the ride. The cool air flow and the lightness of the helmet enhance the fitting and provide an excellent riding experience.
	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.
	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.
	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.
	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.
	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.
