Four options available: clear, blue reflective, silver reflective, and smoke. Simplicity itself, fantastic idea. Three clips push in-between lining and shell and the visor slips into the clip, holding it in place. Lightweight, easily removeable, interchangeable, makes any open face helmet look like a mig fighter pilot's helmet. Gives excellent wind and sun protection and the clear version is ideal for night or day use. Can even fit under the flip up visor of a full-face helmet. Superb.
