Some seriously sweet interchangeable shades just for gals, the Smith Pivlock Asana Women's Sunglasses will keep your eyes protected and your vision crystal clear whether you're running, cycling, or just kicking back looking cool. There's not doubt they're made for getting active, though, with lightweight TR 90 frames that feature two way adjustable hydrophilic nose pads and hydrophilic temple tips that actually get stickier when they get wet, so you'll never have to worry about your shades slipping down your nose when you need both hands on the bars. The Carbonic TLT lenses are crystal clear and oil , water , and dirt resistant, and feature a wide bridgeless and frameless design for and unparalleled field of vision. Even with all this tech, the Asana's party piece is undoubtedly the Pivlock lens change technology, which lets you swap out lenses in a second so you don't waste your precious bike time messing with gear.
