Die-hard cyclists and runners, the high-performance Revo Cusp S Polarized Sunglasses are made for you. Featuring a lightweight semi-rimless frame, the Cusp S stays in place even when you're breaking a sweat thanks to Revo's proprietary Elastomeric nosepads and rubber pads on the inside of the temples that comfortably hug your face. But what separates Cusp S from other performance sunglasses is the lenses. The panoramic lens shields your eyes from all angles, ensuring that you have a crisp, clear view of the road ahead. And since you won't have to worry about your lenses fogging up-thanks to four discrete ventilation holes, the only thing holding you back from biking or running on a misty morning is, well, you.
