The ua Double Down resurrects a classic lens shape and modernizes it with mounted lenses on the surface of the frame. Its feather-light appearance merged with a forged alloy chassis creates a stance that sets the stage for sport luxury. Armoursight lenses: enhanced peripheral vision (vision is up to 20 percent better edge to edge), distortion-free vision (see what's really there without image displacement), military-inspired impact-resistance (up to 10X stronger than polycarbonate lenses). ua Double Down sunglass offers an adjustable nose pad that molds to your shape for a secure, customized fit. And three-point grip provides you with soft, rubber grips at your nose and temples for more comfort and stability..
