Arai Defiant-X Shelby Red Full Face Helmet
Features
• 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 neckroll 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
