Arai XD4 Helmet

The Arai XD4 Helmet is a good choice for those who are looking for a helmet that offers both protection and comfort. The helmet features an aerodynamic design that helps to reduce wind noise and drag, and it also comes with a number of ventilation ports that help to keep your head cool while you’re riding. The XD4 also features a five-point harness system that helps to keep the helmet in place, even in the event of a crash. And, finally, the helmet is lined with Arai’s signature Bio-Dri fabric, which helps to wick moisture away from your skin.
