COSTA DEL MAR FANTAIL SUNGLASSES

The Costa Del Mar Fantail Sunglasses are a premium, high-performance optical management system engineered for backcountry operators and precision anglers requiring rapid environmental adaptation. Moving away from uncalibrated, casual eyewear that distorts surface definition, slips under high-speed vessel transit, or causes ocular fatigue from prolonged glare exposure, this advanced high-wrap frame matrix organizes your visual workspace in a highly protective, low-profile layout built for demanding marine environments and streamlined clarity.

Key Features:

• 580® Advanced Polarization Light Core: Form-engineered with Costa's proprietary color-filtering lens matrix to deliver an uncompromised balance of harsh yellow light reduction and enhanced red, blue, and green definition, exposing subsurface structures and tracking targets with absolute clarity.
• Bio-Resin Co-Molded Frame Geometry: Fabricated with a heavy-duty, eco-friendly TR-90 nylon chassis featuring a tight, high-wrap profile to amplify peripheral light blockage, filtering out side-glare vulnerabilities and wind intrusion for maximum optical sealing.
• Hydrolite™ Non-Slip Secure Construction: Outfitted with specialized Hydrolite rubber nose and temple pads that increase tactile grip as moisture levels rise, working alongside impact-resistant, scratch-proof lens elements to eliminate frame slippage and tracking lag during high-intensity angling operations.
