You value independence. You're self-defining. What you believe in is Yours, and Yours alone. For riders looking to establish their own identity. The Defiant-X is Your self-defining helmet.

The Defiant-X has Arai's INTERMEDIATE OVAL (IO) interior fit shape.

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 Arai's 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.
5 mm Peel-Away Cheek and Temple Pads: Arai's exclusive 5 mm peel-away surface pads on both sides of the headliner and in the FCS Cheek Pads give you the option of 5 mm 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.
Pro Shade System Compatible: This model accepts the optional Pro Shade System (sold separately).
DOT and SNELL certified.

Note: Fluorescent and/or bright finishes fade over time and exposure to sunlight. This is normal and is not covered by warranty.

MEASURING INSTRUCTIONS

1. Measure your head size. To do this, pass a tape measure horizontally around your head at a height of about one inch above your eye brows. When done properly, you will have measured the largest part of your head.

2. Check your measurement with the helmet sizing chart and select the closest size. As the helmet may not always meet your head size exactly, and your head measurement may fall between two sizes, first try the smaller size.

WHEN YOU RECEIVE YOUR HELMET

1. Expand the helmet opening by pulling outwards on each chinstrap, and slide your head into the helmet. If you are unfamiliar with helmets you may be reluctant to pull the helmet down, as it may feel too tight. Even if the helmet is difficult to put on, please use the smallest helmet possible. The helmet should feel snug. If the helmet is not tight, it is too big for you. New helmets will break in and loosen slightly over time.

2. Once the helmet is on:

Check that the helmet inner lining fits snugly all around your head.
Check that the top pad presses on the top of your head.
Check that the cheek pads press up against your cheeks. When you open and close your mouth, you should drag your teeth along the inside of your cheeks.
Check to make sure that you cannot easily slide your finger into the helmet along the side of your temple.
Hold the helmet with one hand on each side. Without moving your head, try to move the helmet up and down, and side to side. You should feel the skin of your head and face being pulled as you try to move the helmet. If you can move the helmet around easily, it is too big. Try a smaller size. Please note that during this check, the chinstraps should be properly fastened.
