Whether it's a day of wakeboarding or a game of volleyball on the beach, the Kaenon Jetty Sunglasses' polarized lenses provide crystal clear vision and unparalleled sun protection. The Jetty's revolutionary SR-91 lenses give you both the lightweight durability of a polycarbonate lens and the clarity of a glass lens. The wrap-around design ensures a comfortable, stable fit during the bumpiest boat or mountain bike rides. Kaenon made these shades versatile enough to handle high activity sports as well as the cool down afterwards on the bar patio.
