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

I’ve worn a lot of sunglasses over the years, but these from KastKing are hands down my favorite. The lens coating is sweet. It repels everything. I spend a lot of time near water, and these lenses stay much cleaner than others I’ve tried. The polarized lenses reduce glare significantly regardless if I am fishing, driving, or playing sports. The lenses are very durable. These sunglasses are very lightweight and comfortable. Lots of color options and I am thankful for the 100% UVA and UVB protection. They also come with a hard case and a microfiber pouch which makes cleaning and storing easy. Overall, these feel like premium sunglasses without the premium price.

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.

These can't be beat for the price. I've had expensive mirrored polarized sunglasses from Redfin and multiple pairs from Costa and it seems like they don't last long for the $200 plus price tag. I picked these up cheaper than replacement lenses would've cost and I'm impressed. Even if I got to replace these every 6 months it's cheaper than purchasing boutique sunglasses that I only seem to get about a year and a half out of. The fit is similar to my Costa Slack Tide and Redfin Amelia's except these are super lightweight.

Little bit glarey in the morning sun, but are my go to sun glasses for fishing and driving.

Much lighter weight than I thought they would be. Definitely polarized. Bought the ones with the reflective blue lenses, they give things a nice red tint when you look through them. Fit nicely under my motorcycle helmet and with the bayonet style temples they're easy to put on. I have a large head but they're flexible. We'll see how durable they are.

Great clarity and very light weight. I will use these for bright sunny days on the water. The polarization is good and allows you to see under the waters surface much better. I love the look of these glasses. They look like a much more expensive pair of glasses. Good value for sure.

My husband needed some new sunglasses and I’m glad I found these. They fit him nicely and look great! He was impressed with how clear and sharp the lenses were when he put them on. He compared them with his other sunglasses and said that these were great at reducing glare. He’s very happy with the purchase.

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.
