Review on Arai Helmet Sunblocker: Enhancing Helmet Sun Protection by Tropingzz Cece

It was a little tricky to put this on and get rid of all the air bubbles, I guess the screen had to be removed first but managed it on the second try. You can undercut it a bit if you find it's not in your preferred line of sight. Works very well and is an inexpensive replacement for a fold down sun visor. This seems to prevent the transition lenses of my glasses from darkening, so I find it necessary to wear sunglasses in combination with this for better protection.
