Built to Keep Your Sunglasses Where They Belong
The Costa C-Mono Retainer is the purpose-built companion for your Costa sunglasses. Constructed from high tensile strength monofilament cord, it delivers the lightweight, low-profile security you need when surf, wind, or activity would otherwise send your shades overboard. The flat, ultra-lightweight temple attachments grip the temples without bulk, sitting flush so the retainer disappears the moment you put it on.
Monofilament Construction and Fit
The C-Mono runs 20 inches from end to end, a length designed to drape comfortably behind your neck whether you are paddling, fishing, or just moving through the day. The high tenacity monofilament cord resists stretch and abrasion, maintaining a clean, consistent profile across active use. A Costa-branded logo bead centers the cord and adds a subtle brand signature without adding weight.
The flat, low-profile temple attachments are the defining detail of the C-Mono design. Where bulkier retainers rely on thick rubber cuffs, the C-Mono uses a sleek clip that stays close to the frame, reducing drag and interference on the water.
Universal Compatibility with Costa Sunglasses
The C-Mono Retainer is compatible with all Costa sunglasses. Whether your frames are from a classic Costa style or a current performance model, the temple attachments are engineered to fit the full Costa lineup without modification. It is the retainer Costa designed specifically for its own frames.
Made in the USA
The Costa C-Mono Retainer is made in the USA, consistent with Costa Del Mar's commitment to quality and domestic manufacturing standards.
Who It Is For
The C-Mono is built for anyone who wears Costa sunglasses and cannot afford to lose them. Surfers, anglers, paddlers, and everyday wearers all benefit from the security of a reliable retainer, and the C-Mono's slim profile means it adds retention without adding bulk. It pairs naturally with Costa's performance polarized frames for a complete on-water setup.
