Costa C-Line Adjustable Retainer

The Costa C-Line Retainer offers a clean, low-profile way to keep sunglasses secure without adding unnecessary bulk. Its ultra-thin design and lightweight wire construction provide a barely-there feel, making it comfortable for long days on the water, at the beach, or during everyday wear.

Measuring 20 inches from end to end, the C-Line Retainer provides enough length for comfortable movement while keeping eyewear close at hand. The streamlined wire design pairs easily with Costa sunglasses and stays out of the way while fishing, boating, traveling, or spending time outdoors.
