Built to Keep Up With Your Adventure
The Costa Del Mar Bowline Silicone Retainer is a purpose-built eyewear retainer designed for people who actually use their sunglasses hard. Crafted from streamlined silicone, it is flexible enough to move with you and durable enough to handle repeated exposure to sun, salt, and sweat without stiffening or cracking. At 19 inches end-to-end, it fits comfortably around the neck whether you are paddling, surfing, fishing, or simply refusing to lose another pair off the dock.
Adjustable Tension, Zero Bulk
The defining feature of the Bowline is its sliding bead adjuster, visible on every unit and bearing the Costa Del Mar marlin logo. Slide it toward the back of your neck to cinch the loop tight against your collar, or ease it out to let your shades hang loose. That single adjustment handles everything from a snug hold during a paddle session to a relaxed hang while you walk the beach. The tapered end-caps slip cleanly over standard sunglass temple tips and stay put without cutting into the frame.
Silicone That Works
Silicone is the right material for a water-sport retainer. It does not absorb moisture, does not degrade from UV exposure the way woven cords can, and wipes clean in seconds. The Bowline keeps its suppleness in cold water and does not go gummy in heat. The streamlined round profile reduces drag and eliminates the bulk of thicker braided or neoprene options, so it disappears behind your neck when you are focused on the water.
Costa Del Mar Quality
Costa Del Mar builds accessories to the same standard as their polarized lenses: made to look good and be tough. The Bowline is designed to pair directly with Costa frames, and the logo bead is a consistent reminder of the brand that has spent decades on the water in South Florida and beyond. It is also a practical choice for any standard-temple sunglass, not just Costa frames.

Frequently Asked Questions
- What is the Costa Del Mar Bowline Silicone Retainer?
- The Bowline is a silicone sunglass retainer from Costa Del Mar. It attaches to the temple tips of your sunglasses and loops around your neck to keep them secure during active use on the water or anywhere else.
- How does the sliding bead on the Bowline work?
- The sliding bead sits at the back of the loop and lets you dial the tension in seconds. Slide it forward to tighten the cord snugly against the back of your neck, or pull it back to let the sunglasses hang loosely when you take them off.
- Will the Bowline fit sunglasses other than Costa frames?
- Yes. The tapered end-caps are designed for standard sunglass temple tips, so the Bowline works with most adult eyewear frames, not only Costa Del Mar styles.
- Is the Bowline retainer suitable for water sports?
- It is built for exactly that. Silicone does not absorb water, resists UV degradation, and wipes clean easily. The retainer is lightweight and streamlined so it stays out of the way during surfing, fishing, paddling, and similar activities.

- The Bowline measures 19 inches end-to-end, providing a comfortable neck loop length for most adults.
