COSTA DEL MAR C-LINE RETAINER

The Costa Del Mar C-Line Retainer is a premium, high-performance eyewear retention system engineered for backcountry operators and open-water anglers requiring rapid environmental adaptation. Moving away from uncalibrated, bulky woven lanyards that absorb sweat, stretch out over time, or tangle in high winds, this advanced marine-grade retention cable organizes your optical workspace in a highly protective, low-profile design built for demanding trails and streamlined clarity.

Key Features:

• Coated Marine-Grade Stainless Steel Core: Form-engineered with a high-tensile, kink-resistant wire cable to deliver an uncompromised balance of ultra-lightweight durability and absolute corrosion resistance against saltwater and UV exposure.
• Universal Non-Slip End Attachment Geometry: Fabricated with streamlined, high-friction rubber templates to amplify frame retention, filtering out slippage vulnerabilities and ensuring a secure, flush fit on a wide variety of sunglass temple sizes.
• Low-Profile Off-Neck Construction: Outfitted with a rigid, streamlined hang arc that stabilizes frame positioning off your neck and clothing, working alongside a sleek profile to eliminate snag hazards and collar friction during high-intensity wilderness navigation.
