KastKing Merced Floating Polarized Sunglasses, Matte Dark Brown Frame, Brown Lens, Buoyant TPX

KastKing Merced Floating Polarized Sunglasses are lightweight, water-ready shades with polarized TAC lenses and frames that naturally float, built for anglers and anyone active on the water.

Designed specifically for boating, fishing, kayaking and beach days, the Merced blends buoyant TPX frames with high-contrast polarized optics and a durable PuriVex lens finish. The combination reduces glare, resists surface damage, and stays comfortable during long hours outdoors. These sunglasses include protective storage and a cleaning pouch so your lenses stay clear when you need them most.

How do these sunglasses improve visibility on water?

The Merced lenses are polarized to cut reflected glare from the surface of lakes, rivers and the ocean, making it easier to see beneath the water and reducing eye fatigue. Lenses are precision-tested to avoid distortion so objects remain sharp across the field of view.

• 0.75mm polarized TAC lenses for strong glare reduction
• Double decentering test to prevent visual distortion
• 100% UVA/UVB blocking for full-spectrum protection

Will these sunglasses survive salt, sweat, and rough use?

The Merced frames are made from TPX, a lightweight, UV-stable material that resists impact and keeps its shape. KastKing’s PuriVex coating on the lenses repels oils, salt, and dirt while minimizing scratches, prolonging clarity in rugged environments.

• TPX frames: light, impact-resistant, and UV-stable
• PuriVex coating repels oil, salt, and moisture
• Included hard case protects lenses during transport

How comfortable and secure will they feel during long outings?

Flexible EMS temples adapt to your head for a secure fit without pressure points, even in hot conditions; the wide temple wrap also helps block peripheral light. The featherlight construction reduces fatigue, allowing comfortable wear for extended fishing trips or all-day boating.

• EMS temples for flexibility and long-term comfort
• Wide-wrapping temples reduce side glare
• Featherlight frame minimizes pressure during long wear

What comes with each pair and how should I care for them?

Each Merced pair ships with a molded hard case for safe storage and a Prym1 camo microfiber pouch that cleans lenses without harming coatings. Rinse with fresh water and wipe with the microfiber pouch to maintain the PuriVex finish and avoid abrasive damage.

• Molded hard case for impact-resistant storage
• Prym1 camo microfiber pouch doubles as a cleaning cloth
• Cleaning tip: rinse salt or sand before wiping to avoid scratches

Who is this for? The KastKing Merced floating polarized sunglasses suit anglers, boaters, paddlers and outdoor lovers who need dependable glare reduction, a lightweight feel, and eyewear that won’t sink if dropped. They’re a practical choice for anyone spending serious time on or near water who wants durable optics, reassuring floatation, and a comfortable fit without adding bulk.
