Brand: Bell Racing
This lightweight guard is designed to deflect the driver's breath away from the shield to prevent fogging. We have also found that it helps minimize dust from the chin bar intake vents getting in the driver's eyes.
A stiff but pliable plastic "bill" along the front edge slips between the helmet chin bar and chin padding. Contoured, stretchy neoprene fabric covers the nose.
Although the deflector is made by Bell, it has been a good fit in just about every helmet brand we have tried.
