The Costa Del Mar Loreto Polarized 580P Sunglasses are laid-back, easy-going, smooth, svelte, and more than suitable for any summer fling. Their polarized lenses virtually eliminate glare, block 100% of UV rays, and are highly impact and scratch resistant. These top-shelf lenses are housed in a metal Monel frame with nose and temple pads to ensure a comfortable fit, while the included hard case protects your new favorite shades after dark.
