What Our Gearhead(R) Experts Are Saying:"I grabbed the Lineup ChromaPop for days when I want a casual frame that still performs. The ChromaPop lenses genuinely change how much detail you pick up on the water or the trail, and the polarization keeps eye fatigue from creeping in on long sunny days."Some days call for a pair of sunglasses that can handle the drive to the trailhead, the hours on the water, and the walk back to the car without skipping a beat. The Smith Lineup ChromaPop Polarized Sunglasses are built for exactly that kind of day - a relaxed, large-fit frame with optical technology that punches well above its casual appearance. ChromaPop lens technology filters two wavelengths of light that cause color confusion, sharpening contrast and bringing out detail in ways that take a minute to get used to in the best possible way. Polarization cuts surface glare on water, pavement, and snow, reducing the eye strain that builds up on long days outside. The Evolve frame keeps weight low without sacrificing durability, Megol nose and temple pads hold their grip even when things get warm, and the base 4 curve keeps distortion minimal from edge to edge. A microfiber pouch is included to keep the lenses protected between uses.
