Arai Defiant-X Helmet.
Aggressive styling that projects the strength within. Arai's PB-cLc shell and one-piece, multi-density EPS liner deliver unparalleled protection. Mouth vent with internal shutter enhances the strong shell design. The Defiant-X comes standard with a VAS Max Vision faceshield to provide better visibility in all seasons and for all types of riding. The VAS shield is smaller and lower than the previous design with adjustable air intake vents that provide improved sealing, which decreases road noise and water intrusion.
- 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.
- 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.
- DUAL FUNCTION FRONT DUCT :
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.
- 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.
- 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.
- 5MM PEEL-AWAY CHEEK & 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..
- 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.

To find the correct size helmet for a person's head:
1. Measure the head circumference one-inch above the eyebrows and ears
2. Using the circumference measured, use the size chart below to find the approximate size
3. Once you have tried on the helmet it should feel snug equally around the head. The helmet should not feel too tight or too loose at any point around head.
***Please remember that all head shapes vary slightly and that this sizing chart is to be used as a starting guide, not an exact guide.
