If you're an active woman you're familiar with sweat and you're probably used to your sunglasses fogging up, slipping down, or just plain making it worse. Oakley's Rev Up sunglasses solved all of those problems by applying the sport innovation Oakley is known for, to an on-trend silhouette. Using their Advancer™ technology, you can easily open up airflow and eliminate fogging, while the Unobtanium™ nosepads keep your shades in place no matter how much you sweat. Despite having all of the attributes of a pair of sport performance sunglasses, Rev Up was designed to look fashionable with large lenses, sleek lines and delicate details. So whether you're running errands or running in a marathon, Rev Up is your perfect fit.
