Features
• Style that matches form and function, the Arai Defiant-X was created with aggressive styling that projects the strength within
• 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
• When open, air flows freely into the helmet and 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
• 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
• 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 neck roll exhaust ports keep the back of the head comfortable by removing hot air as well
• Featuring our anti-microbial material, using a low acidic fabric to help maintain a balanced pH level with the skin
• This material is also odor resistant helping the helmet stay fresher, longer in between cleanings
• 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
• The fixed chin curtain is 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
• The chin curtain is made with water repellent materials it helps block rain and will not weigh down with water
