HJC Atara helmet

The HJC Atara helmet benefits from all 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 lightweight, easy to adjust to your head size and does not compromise on safety. As with all other HJC helmets, the inner padding is removable and washable, keeping the interior clean and the head cool. The helmet is also equipped with more classic features such as an adjustable occipital cradle, goggle holder, shoulder strap separator and X-Static anti-bacterial padding.

Wind tunnel tested
HJC helmets are laboratory and 'real life' tested to meet the highest quality standards. HJC is one of the very few helmet companies with its own wind tunnel to test aerodynamics, ventilation, noise and more. The HJC wind tunnel laboratory measures aerodynamic forces under various riding conditions to improve helmet performance.

Aerodynamic Design
Coming from MotoGP helmet design experience, HJC's designers and engineers have become experts in aerodynamics and ventilation. Aero helmets, as the word suggests, are more aerodynamic than the traditional racing bike helmet, but with compromised ventilation performance. With HJC helmets, this compromise is greatly reduced. HJC offers probably the best semi-ventilated helmet on the market .... Save Watts with HJC helmets!

Ultra Lightweight
HJC bicycle helmets are designed with precise measurements in order to achieve the lowest possible weight. Density, positioning, shapes and materials play an important role in weight optimisation.

Features

Removable and washable inner padding.
Anti-bacterial X-Static padding.
Ultra Lightweight.
In-Mold Construction: In-mold is a method of welding the EPS together with the outer polycarbonate shell for greater structural strength.
Certification: CE EN 1078.

Tecnologie

Venturi Dynamics
Al fine di ottenere la massima ventilazione, un adattamento tecnico del principio di Bernoulli viene applicato ai modelli aerodinamicamente migliorati di HJC. In movimento, la velocità del flusso superficiale generalmente aumenta mentre procede verso la parte posteriore del casco. Attraverso le differenze di pressione, l’aria fredda dall’aspirazione frontale viene estratta attraverso lo sfiato posteriore dissipando il calore interno e garantendo al ciclista una ventilazione ottimale e un flusso d’aria perfetto durante la guida.

Costruzione In-Mold
In-mold è un metodo che consiste nel saldare l’EPS assieme alla calotta esterna in policarbonato per una maggiore resistenza strutturale. Ciò migliora la protezione del ciclista fornendo un rinforzo compatto e conferendo al prodotto una finitura perfetta.

Sistema avanzato di ventilazione
Una certa quantità di aria passa attraverso il condotto di aspirazione dell’aria anteriore, quindi circola all’interno del casco ed infine esce dal condotto di scarico. Il flusso d’aria interno viene quindi migliorato per raffreddare la testa e dissipare il calore.
