Don't let the sun get in the way of your fun! These 100 percent UV-rated Sunblockers reduce glare, tension, and fatigue so you can ride longer and more comfortably all day long. Just wet the Sunblocker and slide it into position on the inside of your faceshield, right above your line of sight. It can be removed without leaving any residue and transferred to another helmet. Fits most helmets except Arai helmets with eyebrow vents.
