Smith's Parallel Max 2 Polarized Sunglasses provide larger coverage for medium face sizes, and feature stunning optics that ensure clarity. Carbonic TLT lenses deliver an unobstructed view while polarization cuts through glare on the water or road. The TR90 frame is lightweight, yet durable, and features auto-lock hinges to secure the position on your face. Megol nose and temple pads resist slipping when you start to sweat.
