After a long day on the bike, you should be thinking about cracking open a cold one with your buds, not sore spots behind your ears. Ready for the trail, road, or CX course, our Smith Ruckus sunglasses are made for all-day comfort with thin, no-slip temples that are designed to work with your helmet. The raised-brow design with two interchangeable ChromaPop(TM) lenses gives you great peripheral vision in the riding position and adds enhanced color and detail to your view. When the afternoon sun starts to dip, easily swap lenses using our PivLock(TM) technology and get ready to enjoy the sunset from the saddle.
