All day cycling and running marathons call for Optic Nerve's Polarized Sequence Sunglasses. Their SideSwipe interchangeable system lets you change the included lenses at a quick flip of a switch. Each polarized lens blocks obnoxious glares, and a hydrophobic coating that wicks away water, oil, and dust. The lenses also provide 100% UV protection and meet ANSI Z80. 3 standards for clarity and resistance. Optic Nerve paired these lenses with a high durable TR90 frame, and the frame's adjustable temples feature slip resistant Tactilite rubber.
