Arai Defiant-X Shelby Helmet

Arai Defiant-X Shelby Helmet Fitment

Intermediate Oval: 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.

So for more than three decades, Arai has pioneered different shapes – and even different proportions within those shapes – in our various helmet models, working to offer a better fit for more people.

Arai Defiant-X Shelby Helmet Technical Features:

Arai Defiant-X Shelby Helmet PB-CLC Shell: Peripheral Belt construction born from F1 technology. The PB-cLc shell features technology developed in the highest level of racing in the world: F1. The Defiant-X shell is constructed from the layering of many materials with proprietary adhesives which allow for a larger eye port. Protection is further enhanced by the Super Fiber Belt that strengthens the shell like the bands of a barrel. This distinct belt resists the widening of cracks encountered in an impact while evolving our most advanced shell in strength, weight, and protection.

Arai Defiant-X Shelby Helmet New IR Neck Roll Pad: When open, air flows freely into the helmet. When closed, the QVF-2 Duct prevents air from entering and functions as an exhaust duct, allowing hot air to be pulled from the helmet interior.

Arai Defiant-X Shelby Helmet Anti-Microbial Interior: Featuring our anti-microbial material, using a low acidic fabric to help maintain a balanced pH level with the skin. It is also odor resistant helping the helmet stay fresher, longer in between cleanings.

Arai Defiant-X Shelby Helmet Fixed Chin Curtain: Larger and helps to block out wind noise and control airflow efficiency under the helmet by creating a low-pressure zone in the mouth area, helping to draw breath out of the helmet. Made with water repellent materials it helps block rain and will not weigh down with water.

Arai Defiant-X Shelby Helmet Mouth Vent and Eye-Port Ventilation: To enhance the strong shell design, the open-close shutters are placed inside of the helmet. Air can flow over the mouth for a demist function by opening and closing these shutters.

To further enhance internal airflow, air channels originally designed for the Corsair-X were borrowed and updated and connected to new exhaust ports on the chin bar. This increased airflow reduces fogging potential and increases rider comfort.

Arai Defiant-X Shelby Helmet Rear Duct: The upper QVR-2 rear duct has three vent holes controlled by a single sliding gate. When open, air is pulled from the helmet interior. Additional side and neckroll exhaust ports keep the back of the head comfortable by removing hot air as well.

Arai Defiant-X Shelby Helmet 5MM Peel-Away Cheek And Side-Temple Pads: Arai's exclusive 5mm peel-away surface pads on both sides of the headliner and in the FCS® Cheek Pads give you the option of 5mm more of interior width if needed (minimizing the need to purchase optional thickness pads). Yet another level of fit customization no other helmet brand offers.

Arai Defiant-X Shelby Helmet Pro Shade System Compatible: This model accepts the optional Pro Shade System.
