The Arai Defiant-X Helmet is steeped in style and protection. Building upon the original Defiant, the Defiant-X smooths out its predecessor's aggressive lines to produce a bold yet refined helmet. SFL shell construction is round and smooth to avoid catching on rough surfaces. The shape and materials create a strong shell to disperse energy upon impact. Facial Contour System cheek pads provide a snug yet comfortable fit. Arai's Free Flow System guides air underneath the helmet to improve overall ventilation for hot weather riding. The Arai DefiantX is the result of Arai's legendary quality and attention to detail. Its comfort, protection and style are a triple threat that is tough to beat.
