It’s true now, and it was true then: We’ll do anything to stay on the water longer. In 1983, a group of anglers created Costa Sunglasses to stand up to the harsh light, unforgiving salt and rough conditions of a day at sea. Costa Del Mar sunglasses sold by authorized sellers like Amazon are eligible for all manufacturer warranties. Included is a microbag and cleaning cloth.
