Built to Keep Your Costas Where They Belong
Lose your sunglasses to the water once and you understand the value of a good retainer. The Costa Del Mar C-Line Loop Retainer is a purpose-built eyewear keeper designed to pair with Costa frames and keep them secure during fishing, paddling, boating, and any other activity where your glasses need to stay with you.
The retainer features a thin, flexible wire cord construction that stays low-profile and out of the way. Small loop end-fittings slide over the temples of your Costa sunglasses for a reliable connection, and a Costa-branded center bead adds a subtle brand detail while doubling as a cord length adjuster to let the retainer sit comfortably against the back of your neck.
How to Use the Costa C-Line Loop Retainer
Slide each loop end over one temple arm of your sunglasses until it seats snugly behind the ear hinge. The retainer then hangs around your neck when you remove your glasses, keeping them within reach rather than at the bottom of the water. The fit is intentionally compact so the cord does not interfere with casting, paddling, or any overhead movement.
Why a Loop-Style Retainer
Loop retainers grip the temple directly rather than relying on a friction sleeve, which makes them more reliable on active days when glasses are taken on and off repeatedly. The wire cord construction is lightweight and does not hold moisture the way fabric lanyards can, making it a practical choice for saltwater and freshwater environments alike.
Costa Del Mar Quality
Costa Del Mar built its reputation on performance eyewear for people who spend serious time on the water. The C-Line Loop Retainer carries the same commitment to function and durability into a simple, essential accessory. It is designed to work seamlessly with Costa frames and branded to match.

Frequently Asked Questions
- How do you use the Costa C-Line Loop Retainer?
- Slide each loop end over one temple arm of your sunglasses until it fits snugly behind the hinge. The wire cord then hangs around your neck when you take your glasses off, keeping them secure and accessible.
- What is a loop retainer and how is it different from other eyewear retainers?
- A loop retainer uses small cord loops that slip directly over the temple arms of your sunglasses. Unlike friction-sleeve or strap-style retainers, loop ends grip the temple securely and hold well even when glasses are removed and replaced frequently during active use.
- Will the Costa C-Line Loop Retainer work with non-Costa sunglasses?
- The C-Line Loop Retainer is designed and sized to work with Costa Del Mar frames. Compatibility with other brands depends on the diameter and shape of the temple arm at the end.
- Is the Costa loop retainer suitable for water sports and fishing?
- Yes. The wire cord construction is lightweight, low-profile, and does not retain moisture like fabric lanyards, making it well suited for fishing, boating, paddling, and other on-the-water activities.
- What does the center bead on the Costa C-Line retainer do?
- The Costa-branded center bead is a cord adjuster that lets you set the length of the retainer so it sits comfortably against the back of your neck and does not swing when you are moving.
- Where can I buy the Costa Del Mar C-Line Loop Retainer?
- The Costa C-Line Loop Retainer is available at Island Water Sports in South Florida and online at islandwatersports.com.
