When we're at the beach or out on the water, we're wearing the Costa Caleta Net 580G Polarized Sunglasses for their clarity, sun protection, and eco-friendly construction. The Caleta features Costa's premium Polarized 580 lenses for filtering reflective glare, absorbing harmful UV and HEV radiation, and enhancing reds, greens, and blues for great vision in sunlight. The lenses are also 20% thinner and 22% lighter than the average polarized glasses and sandwich the mirrors between glass layers to make them 100% scratch-proof. As water lovers and anglers, we also like the Untangled frames, which are made from recycled fishing nets to help clean up our waters and reduce our carbon footprint.
