How did cyclists in the ’80s even see around those big, bulky frames? We’ve come a long way since the days of leather chamois and crumbly energy bars. The Smith Reverb performance sunglasses have a modern, 27-gram shield for a panoramic view without the weight of bigger glasses. The PivLock design lets you easily swap between two interchangeable ChromaPop lenses. No-slip nose and temple pads keep your glasses right where you need them around every blind corner and up every brutal climb.
