Costa Del Mar C-Line Sunglasses Retainer

In 1983, a group of hardcore fishermen who spent their days exploring the globe and battling extreme elements came to realize that the sunglasses they were relying on weren't as hardcore as their adventures. Seeing the world in absolute clarity and protecting their eyes was a must. When they couldn't find worthy sunglasses, they decide to build their own. And Costa® was born.

After all these years and all these adventures, Costa's mission has never wavered: to create the clearest sunglasses on the planet for life's great adventures. The patented technology like those found only in Costa lenses and frames are proof that they're succeeding.
