KastKing Merced Floating Polarized Sports Sunglasses A: Matte Black Frame, Smoke for Men & Women, Buoyant TPX

Designed for anglers, boaters, paddlers and outdoor lovers, the Merced combines featherlight construction with durable optics and protective coatings to reduce glare and protect your eyes on the water. The frame is built from TPX (polymethylpentene) for impact resistance and natural buoyancy, while the 0.75mm polarized TAC lenses minimize reflected light and deliver 100% UVA/UVB blocking. Added benefits like PuriVex lens protection and flexible EMS temples make these sunglasses practical for long days in bright, wet environments.

How do these sunglasses keep your gear from sinking?

The Merced uses hollow-feeling TPX frame material that is buoyant by design, so the glasses will float when dropped in water. This keeps you from losing expensive eyewear while fishing or boating and reduces recovery stress on choppy days.

• Featherlight TPX frame that naturally floats on freshwater and saltwater.
• Flexible EMS temples maintain fit without adding weight.
• Wide temple wrap helps keep the glasses stable in waves or wind.

What kind of glare reduction and eye protection do the lenses provide?

The Merced lenses are 0.75mm polarized TAC that cut reflected glare from water, snow and pavement for clearer contrast and less eye fatigue. Lenses pass double decentering tests for low distortion and provide full UVA/UVB protection to shield eyes from harmful rays.

• Polarized TAC optics reduce surface glare and improve visual clarity.
• Double decentering verification to minimize optical distortion and headaches.
• 100% UVA and UVB blocking for sun protection during extended exposure.

How durable are the frames and coatings for active use?

The frame material is UV-stable and impact resistant, with EMS temples that flex instead of breaking under strain. KastKing’s PuriVex coating repels oil, sweat and salt while resisting scratches, keeping lenses clearer and easier to clean after rough outings.

• TPX frame resists impacts, UV degradation, and surface wear.
• PuriVex coating repels oils and salt to preserve lens clarity.
• Molded hard case plus camo microfiber pouch included for storage and cleaning.

What accessories and fit features are included with the Merced?

Every pair ships with a molded hard case for secure storage and a Prym1 camo microfiber pouch that doubles as a cleaning cloth and soft carry sleeve. The temples are shaped for a secure fit and the wide wrap design reduces side light intrusion for better peripheral protection.

• Molded hard case protects frames in a tackle box or bag.
• Prym1 camo microfiber pouch cleans lenses and provides soft storage.
• Wide temple wrap improves fit and blocks side glare for full coverage.

Who is this for? The KastKing Merced Floating Polarized Sports Sunglasses suit recreational and serious water users who want reliable, lightweight eyewear that floats, blocks glare, and resists the wear-and-tear of marine environments. Choose these shades if you fish, boat, kayak, sail, or spend long days on beaches—anywhere glare, salt, and accidental drops are a risk and clear, comfortable vision matters.
