Great Value, Comfortable Fit, and Perfect for Water Activities
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
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. 👍

Great glasses for the price!
great glasses! great quality for the price and everything is so much clearer. great protection for my eyes and comfortable. I can wear these all day without having pressure sensation right behind/above my ears with some sun glasses. They are very stylish too. I use them for every day use or for fishing! i can see fish clearly in the water. would order it again!

Actually, A Solid Buy
Bought a pair of Oakleys and these Kastkings, looking for something quality, stylish, and including Polarization. I have not tried them outside during the day, and I can tell the polarized lenses aren’t as strong as the oakleys, however they make up for it in weight, style, and most importantly cost. They came shipped with tons of protection, which compared to the nearly $300 Oakley that had a sock and crushed flimsy box, was awesome. The matte finish was nice, they fit comfortably, and they fit nice on my 7 1/4 hat size head. They aren’t tight, maybe more on the loose side, but I had to really headbang to get them to start sliding off. So I’d say if you have a bigger head, they might be a good try. I’ll be shipping the oakleys back in the box that the Kastkings came in.

Great quality
My son loves these. The logo is subtle, and the lens color is vibrant, and they seem to be great quality. They're polarized, which is a must in Florida.

Good glasses
My favorite sunglasses. It’s hard for me to find glasses that fit and don’t rest on my cheeks but these are great. And comfortable to be in all day. My only complaint is the coating on the lenses is not very robust. After about a year of wear the coat is starting to flake off the lenses but at the price point I guess I should expect corners to be cut.
