Looking for a lightweight pair of shades with the optical clarity of glass and the impact-resistance of polycarbonate? Pick up the Smith Outlier XL Polarized ChromaPop Sunglasses for exceptional optical clarity, lightweight comfort, and impact-resistant performance. Featuring Smith's ChromaPop polarized lenses, these shades filter out color confusion caused by intersecting visible light wavelengths for increased clarity with exceptional color definition on the brightest, sunniest days. Made of Trivex material, this polarized lens provides the optical clarity normally found with glass. However, Trivex material is ultra-light and more impact-resistant than traditional glass for enhanced comfort and rugged performance. These shades are equipped with a lightweight, durable Evolve frame for long-lasting use, even if you drop or bump 'em on accident. The Megol nose and temple pads provide a secure, comfortable fit when you're on-the-go and sweating in the summertime. Note that this pair of sunglasses fits those with a medium-to-large face size best.
