OO9518 Stunt Devil S – a takedown of Stunt Wing, this sport performance sunglass introduces Oakley Hyper Grip, a new and innovative Oakley technology platform designed to enhance frame retention. Originated from a hypothesis to see if the combination of weight distribution and rotational around your ear play a key role in bounce and nose slip while running. Leading us to Stunt Devil's unique temple design pulling inspiration from duck feet and Hyper Grip earsocks made from a flexible, yet sticky material that molds to your head without causing discomfort or slipping - keeping the sunglasses in place no matter what. Created with athletes and active individuals in mind, Stunt Devil is perfect for anyone looking for a high-performance sunglass that offers superior grip and retention during intense physical activity.
