## Description

KastKingFlatRock Polarized Sport Sunglasses for Men and Women, Ideal for Driving Fishing Cycling Running, UV Protection

## Features

- KEY FEATURES – Oleophobic lens coating repels saltwater, oil, and chemicals - Polarized lenses reduce glare - Impact resistant TAC lenses protect your eyes from flying objects - Block 100% of the harmful UVA and UVB rays - Super Lightweight, durable, and flexible Grilamid frames
- OLEOPHOBIC LENS COATING – Our 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. 1.0mm polarized lenses are comparable to the thickness you would find on much higher priced sports eyewear. KastKing Polarized sunglasses help reduce glare caused by reflected light to improve vision and comfort.
- SUPERIOR AND SUPER LIGHTWEIGHT FRAMES – Made from the same Grilamid material commonly used by the military and in medical applications, our frames are greatly lightweight, extremely flexible, and heat and UV resistant. Grilamid frames are well known for their strength, lightweight comfort, shape integrity, and impact resistance. This ultra-lightweight and malleable material translates to a very comfortable fit.
- BASE LENS COLOR and UV PROTECTION – 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 were best suited for moderate to low light. Green performs well in sunny to overcast conditions. KastKing sunglasses block 100% of the harmful UVA and UVB rays and meet or exceed all U.S. ANSI standards.
- PROTECT YOUR EYEWEAR – KastKing sunglasses include a molded custom hard case for storage and a custom Prym1 Camo microfiber pouch which can be used for cleaning as well as 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 dip them in saltwater or dry with a paper towel.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Value, Comfortable Fit, and Perfect for Water Activities
*by W***. on March 16, 2025*

I purchased the KastKing FlatRock Polarized Sport Sunglasses for an upcoming cruise to the Bahamas and a fishing trip. I specifically needed blue mirror lenses for better visibility on the water, a comfortable and secure fit, and a good price—these sunglasses deliver on all fronts.The polarization is solid, cutting glare effectively while enhancing colors, making them ideal for fishing, boating, and general outdoor use. The lightweight frame is comfortable enough for all-day wear, and they stay put even during movement—no annoying slipping down the nose.I also considered Knockaround sunglasses, which I've used before, but I’m glad I went with the FlatRock style. The design works well with my long face and angular features, providing both a stylish and functional fit.For the price, these are an excellent alternative to more expensive polarized sunglasses, and they don’t feel cheap. If you need reliable eye protection for driving, fishing, cycling, or any outdoor adventure, these are a solid pick.

### ⭐⭐⭐⭐⭐ Wow, these are fantastic
*by J***S on June 19, 2024*

I may have to try a KastKing spinning reel after wearing these (Normally a Penn guy) because the quality of these sunglasses is that excellent.Let's start with what's obvious; the looks. First, there's no mistaking these for cheap, off-the-rack shades. KastKing is clearly employing a higher-end manufacturing process to produce these, and at least for me this size is perfect.I want full coverage for my eyes (beach - surf fishing), and to me a lot of frames on the market appear to have been designed with a smaller head in mind. These are not like that. They're large enough to cover my eyes without being too big. They're also not "cat-like" which for my taste makes then more wearable.Next thing has to be the weight. Really wow. They're amazingly light. I can barely tell that I'm wearing them, and I love that they are pliable, a definite plus.Polarization, check ✔️. Mirror lens, check ✔️. Eye-soothing tint, ✔️. Comes with a great case, ✔️ Affordable price, ✔️.Seriously, I may just have to try out that spinning reel, but whatever the case I'm definitely a fan of the sunglasses. So much so, in fact, that I think I'll get a pair for my wife, too.KastKing, please take a bow. 👍

### ⭐⭐⭐⭐ Bought twice!
*by L***. on March 1, 2025*

This is my second purchase of the same glasses. Bought them last summer while working as a lifeguard. They are lightweight and comfortable, the polarizing effect is really good for how inexpensive they are. The frames themselves are durable but the coating on the lens was not, hence why I am buying them again. I love the color effect of these specific lens, it still feels bright but good for sensitive eyes. They fit my face very well and are even good for outdoor exercise!
