No matter where you drop anchor, Costa's Egret will be there with laid-back style and comfortable fit. Its round shape, 100% UV protection polarized lens and wave-textured integrated rubber work together to keep these frames in place even if you're constantly on the move. Named for the Egret, a powerful, beautiful, and water-loving bird, these sunglasses combine Monel® metal and Bio-Resin Nylon together to create frames as durable as they are beautiful.
