The Compact Mirror attaches to sunglasses or a helmet to allow cyclists and other outdoor enthusiasts to see behind them without turning their heads, much like a rearview mirror on a car. The Compact Mirror works best on regular glasses or a helmet and does not work with wrap around glasses.
Other features include:
-Three pivot points for optimal adjustability
-Frameless mirror means uninterrupted field of vision
-Compact size provides a wider field of vision than the Original Mirror
