DescriptionThere's a time and a place to sweat the details. Designing the Riptide, we did just that. These Smith sunglasses are a classic, Italian-made style with bio-based frames. Spring hinges expand the fit at the temples. The extra flex is not only more comfortable, but feels snug through runs and bike rides. These glasses come in two lens options, each with glare-cutting polarization. ChromaPop lenses boost detail, color and clarity while ChromaPop Glass has the added benefit of high scratch resistance.Product DetailsVisionChromaPop Glass polarized lenses cut glare and enhance color and contrast, and are highly scratch-resistantSmudge and moisture resistant coating for easy cleaning and clear opticsAnti-reflective coating improves clarity and reduces eye strainFit / IntegrationMedium-large fit, medium coverage6-base lens curvature provides a modest wraparound fitMegol nose and temple pads provide non-slip grip so glasses stay putSpring hinges self-adjust to your face for a snug, comfortable fitFrameEvolve bio-based frame material is lightweight and durable
