Named after the small, chilled-out town in the Sea of Cortez, the Costa OCEARCH® Loreto sunglasses are full frame and adventure friendly. Whether it's hanging on the coastal cliffs for which these Costa men's or women's sunglasses get their name or on any adventure on land or sea, these durable, versatile, polarized sunglasses can handle their own for any explorer.
