Shoal - Tortoise - ChromaPop Glass Polarized BrownFrom beach to paddleboard or knee deep river, eye protection on the water is serious business, and the women's Smith Shoal sunglasses do it in style. The cat eye inspired shape offers a subtle, retro feel that looks as great on the dock as it does in town. Low profile side shields add peripheral light coverage while ChromaPop polarized lenses cut glare and enhance contrast to reduce eye fatigue when you're in the sun all day long.
