Costa Del Mar C-Line Loop Retainer 20-Inch – Silver/Black | Secure Sunglasses

Never misplace your sunglasses again with the Costa Del Mar C-Line Loop Retainer. This slim, flexible accessory keeps your frames close at hand whether you’re crossing a breezy boardwalk, hurrying from dock to deck, or casting lines on a sunlit morning. The retainer uses an ultrathin, lightweight coated wire and a subtle logo bead to hold your Costa sunglasses securely in place without adding bulk. It’s designed to feel unobtrusive, letting you focus on the view rather than constantly adjusting straps.

At 20 inches from end to end, the loop offers versatile wear options. You can wear it around your neck for easy access, attach it to a cap, or let it rest along your collar while you move through salt spray or a spray from a fountain. The design is compatible with all Costa sunglasses, so you can pair the same retainer with different frames as your style shifts. When you shop from authorized sellers, Costa products come with the manufacturer warranties and guarantees that accompany the line, providing reassurance alongside practicality.

Durable and discreet, the coated wire resists weather and sweat, while the logo bead adds a touch of branded craftsmanship. The light profile helps minimize snagging during outdoor activities, and the secure fit helps prevent accidental drops when you lean over rails, reach for gear, or climb aboard. If you purchase from an authorized retailer, you’ll benefit from Costa’s warranty support and dedicated customer care.
