Troy Lee Designs GP Air Tilt Vented Youth Jersey

Purpose-built for the street. A new benchmark in comfort, quiet, stability, and ventilation. Arai applied the same tireless 24-7 focus devoted to our race helmets to designing it, refining and adapting proven concepts to a new purpose. On the rounder end of the head shape spectrum, the Quantum series has always been the “go-to” helmet of choice. The new Quantum-X brings that shape back in a feature-rich package.

Notice: Fluorescent finishes used in certain models of Arai helmets are not covered by warranty and may fade with the passage of time and exposure to the elements. 

Arai is the only company offering multiple interior-fit shapes to better address the infinite variety of riders’ head shapes and sizes.

No one pays more attention to the subtle variations and infinite possibilities of the human head shape than Arai. Why? Because it’s the secret to getting the best comfort and fit.

And Arai is nothing short of obsessed with putting you into the best fitting, most comfortable helmet possible – because that´s who we are.

The Quantum-X has Arai’s ROUND OVAL (RO) interior fit shape.  Shorter front-to-back and a little wider side-to-side (as compared to Intermediate Oval).*

*A Helmet needs to be tried on in order to determine a proper fit.
