Revo's Polarized Cusp C Sunglasses mix a sleek, everyday style into a sporty design suitable for cycling and running. Their polarized Serilium lenses provides 100% protection against glares, UVA, UVB, and UVC light, as well as high light absorption and blue and HEV light blockage. The semi-rimless frame ensures lightweight comfort, and the Elastomeric nosepads work with the rubber temple pads to prevent slippage after you work up a sweat.
