From the brand, our vision is to achieve affordable innovation through novel concepts and ingenious designs. Our mission is to provide lasting memories of enjoyable fishing experiences for everyone through innovation and technology.

The KastKing Flatrock Polarized Sunglasses feature a lightweight, pliable Grilamid frame for extended comfort during long periods of use. The frames are built to survive years of active use, being ultra-lightweight, extremely flexible, resistant to heat and UV rays, and possessing excellent memory to retain their shape.

KastKing's polarized lenses are manufactured using Japanese and German raw materials to produce a lens with excellent optical quality, being ultra-lightweight, tough, and scratch-resistant. These lenses pass a double decentering test to ensure the highest standards of visual clarity with no optical distortion. Polarization helps reduce glare caused by reflected light, improving vision and reducing eye strain, and allowing anglers to see into the water and spot fish, which is essential for sight fishing. All KastKing eyewear lenses block 100% of harmful UVA and UVB rays.

The lenses are protected with a tough oleophobic coating to protect against dirt, dust, oil, chemicals, and harsh saltwater conditions. The FlatRock polarized sports sunglasses are designed for fashion and function, ideal for driving and sports activities such as biking, running, boating, fishing, and golfing.

The key features include an oleophobic lens coating that repels saltwater, oil, and chemicals, polarized lenses that reduce glare, impact-resistant TAC lenses that protect your eyes from flying objects, 100% blocking of harmful UVA and UVB rays, and a super lightweight, durable, and flexible Grilamid frame. The sunglasses come with a 30-day money-back guarantee.

The oleophobic lens coating creates an oil-resistant, anti-fingerprint surface that is impervious to dirt, dust, oils, and other particles, resulting in a surface that is easy-to-clean and maintains a cleaner lens longer than untreated lenses. The 1.0mm polarized lenses are comparable to the thickness found in much higher-priced sports eyewear.

The Grilamid frames are greatly lightweight, extremely flexible, and heat and UV resistant, known for their strength, lightweight comfort, shape integrity, and impact resistance. This ultra-lightweight and malleable material translates to a very comfortable fit.

The smoke lenses are ideal for bright sunlight with the most realistic color reproduction and work well in medium light and partial shade. Brown lenses increase contrast and depth perception, ideal for cloudy to sunny conditions. Copper lenses are best suited for moderate to low light, and green lenses perform well in sunny to overcast conditions. All KastKing sunglasses block 100% of the harmful UVA and UVB rays and meet or exceed all U.S. ANSI standards.

To protect your eyewear, KastKing sunglasses include a molded custom hard case for storage and a custom Prym1 Camo microfiber pouch for cleaning and storing your sunglasses. To avoid lens scratches and lens coating damage, clean your lenses with a clean microfiber cloth or lint-free cloths and fresh warm water, never dipping them in saltwater or drying with a paper towel.
