Marine-Grade Sunglasses Retainer Built for the Water
The Costa Del Mar Fathom Cord keeps your sunglasses within reach during every activity, from paddling to fishing to a day at the beach. Made from marine-grade soft nylon, the braided cord is engineered to handle moisture, salt, and sun exposure without stiffening or degrading. At 28 inches end to end, it rides comfortably around the neck while giving you enough drop to stow your glasses instantly when you need clear vision.
Secure Fit on Most Sunglasses
The Fathom Cord is designed to fit all Costa Fathom sunglasses and most other sunglasses with co-injected temples. The slip-fit end attachments stretch over the temple tips and lock in place, holding the frame firmly without cracking or distorting the temple. Installation takes seconds: slide each end attachment onto a temple tip and the cord is ready to go.
Adjustable Logo Bead
A Costa-branded logo bead threads onto the cord and slides to set your preferred hang length. Position it snug against the back of your neck to keep the glasses flush to your chest when not in use, or let the cord hang looser for a more relaxed carry. The bead locks in place once adjusted so it does not shift during activity.
Genuine Costa Del Mar Accessory
Costa Del Mar is an American brand built around performance polarized eyewear for anglers, surfers, and water sports enthusiasts. The Fathom Cord is an official Costa accessory, carrying the same quality standards as their lens and frame lineup. It pairs with Costa Fathom frames and functions as a universal sunglasses retainer cord for most co-injected temple styles.
