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

For the price, these are hard to beat... I didn't think you can beat them! I actually bought a second pair, different tint/lens lady week when they were on sale for $26.99 which is a ridiculously good deal!!! I currently have 3 pairs of Costas (I've had more at least 3 more pairs in the last 20+ years) and I can't really see a difference as far as vision in the water. The frames is the Costas are better, stiffer, stronger, etc, (the frames of Costas are not nearly as good as they used to be before they got sold and started being made in China around 10 years ago) but as far as blocking sunlight reflection on the water and visibility I can't really see any difference. I mean for $30, you can buy about 7 pairs of these for the price of 1 pair of Costas. I highly recommend these glasses if you're a fisherman and don't want to spend $200+ for a pair of polarized glasses. I still sometimes wear my Costas and polarized Oakley's but that's because they are prescription lenses (I'm nearsighted), but for the last month when I'm wearing my contact lenses I wear these.

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.

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

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.

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 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.
