The Arai Difference: It's The One You Can See, Feel, Touch. And Trust. The simple truth is, while there are a lot of helmets out there, there is still only one Arai. Their name and reputation have been forged over time, the hard way. Which means they haven't devoted three generations of the Arai family to the singular goal of no-holds-barred excellence just to turn out helmets like everybody else's. Arai alone has the experience, the quality, and the trust that truly set them apart. The Arai XD4 Face Shield replaces the category-leading Arai XD4's O.E. face shield.
