Check out this new arrival from Costa Del Mar, in their Patriot Collection! The "American Sky" features a unique, eye-catching design which depicts the contrast between a stunning all American blue sky and wispy white clouds! Like all Costa Del Mar optics, the Women's Waterwoman 580G Polarized Sunglasses don't tread far from watery adventures. These shades are designed for those who aspire for watery adventures every day, and they have performance-oriented features geared for more active lifestyles. Their polarized lenses deflect all those harsh rays, and they're made of 580G glass for superior clarity, scratch-resistance, and a thin light frame. Costa has produced this frame out of a bio-based resin for an environmentally friendly construction that doesn't harm the beaches you love to relax on. Hydrolite pads cover the nose and temples to ensure a solid grip when things get wet.
