Evil Eye Pro Small a127 is a result of feedback from world-class cyclists in three major categories: vision, protection and fit.  Evil Eye features Adidas LST Anti-fog lens system in an adjustable 10-base frame that you can barely feel on your head. Comes with 2 Quick-Change lens sets and a Sweat Blocker foam band line on the top rim. Features breakaway hinges for safety. An optional Rx insert can be secured behind the lens, or removed for use with contact lenses.
