I bought it to use on my 3/4 helmet it fits good and covers a good amount of my face , it allows wind to go around and out of the helmet. I did continue to use my clear safty glasses with it so at night I can just pop the unit off and keep riding . The smoke color is good for daylight and not super dark also
This allows me to use my half helmet on hot days and still block wind from my eyes. Love it.
Great product. Easy installation.
