Features
- KEY FEATURES Polarized lenses reduce glare, impact-resistant TAC lenses protect your eyes from flying objects, lightweight, durable, and comfortable Grilamid frames, non-slip nose and temple pads, full wrap design for maximum coverage, block 100% of harmful UVA and UVB rays, and include a molded custom hard case for storage plus a Prym1 Camo microfiber pouch for cleaning and storage
- PURIVEX LENS COATING - KastKing PuriVex lens coating repels water, oil, salt, and dirt while resisting scratches. This protective layer keeps lenses cleaner, clearer, and more durable, even in tough marine and outdoor environments
- SUPERIOR LENSES 1.0mm polarized lenses are comparable to the thickness found on much higher-priced sports eyewear. KastKing TAC (Triacetate) lenses pass a double decentering test to ensure there is no optical distortion which can cause eye strain and headaches. KastKing Polarized sunglasses help reduce glare caused by reflected light to improve vision and comfort
- PREMIUM FRAMES Made from the same Grilamid material commonly used in military and medical applications, KastKing sunglass frames are lightweight, extremely flexible, and heat and UV resistant. Grilamid frames are well known for their astounding strength, lightweight, comfort, shape integrity, and impact resistance. This virtually indestructible, ultra-lightweight, and malleable material translates to an amazingly comfortable fit, while tacky nose pads help prevent slipping
- 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 partly cloudy to sunny conditions. Copper lenses are best suited for moderate to low light. KastKing sunglasses block 100% of the harmful UVA and UVB rays and meet or exceed all U.S. ANSI standards

Start of a new kayak fishing season in Florida requires New Sunglasses.. ok I lost my old pair.. Picked up a pair of these KastKing Osage Sunglasses and they are fantastic. Great fit. They do NoT sit to close to my face.. no eyelash rub. Lens clarity is fantastic.. I know Seeing in HD is not a real thing but glasses like these make you think it should be. The polarization helps you see the fish in shallow water. Great price. Not only do you get the Sunglasses but they also come with a hard case and soft case.. all for a very low price.

Purchased mainly for driving and daily use. Pool and beach a few times a year. These are great for all my needs totally functional and durable. Had for about a month so far. Very lightweight and comfortable. Wear them about 6-8 hours and does not hurt. Full coverage as advertised wraparound. Happy for the case and cleaning cloth comes at no extra charge. Case is lightweight and durable. The price point is great for all its features. Don’t feel like they are cheap.

Comfortable, very clear view that blocks reflections on the surface of water and helps you get a clearer view in somewhat murky waters. Great value for the price and comes with an awesome case!

The glasses are awesome. The best sunglasses I've ever come across, in fact. I've never understood how anybody would be crazy enough to drop a bunch of money on a pair of way overpriced sunglasses any more than I've understood people paying what they are paying for a way overpriced lousy cup of coffee. These sunglasses aren't really cheap, but they aren't massively overpriced either, and are probably every bit as good as the massively overpriced brands. They are light in weight, comfortable to wear for hours on end, and do a fantastic job at shielding your eyes from bright sunshine, glare, and UV rays. I love how well they shield my eyes, and my eyes instantly relax the instant I put them on while driving in our ridiculously intense desert southwest sunshine. I like this brand so much I now have a half a dozen pairs in assorted lenses for different weather conditions and a few different frame styles. Some I like a little better than others, but this particular style is my favorite as they cover so much area on my face, and let so little glare in around the peripheral areas of the glasses. Go ahead and spend 100-200-even 300 bucks on a pair of sunglasses. They can't be any better than these when it comes to shielding your eyes for the sun, and you can get these for less than 30 bucks. I have Ray-Bans, I've tried Oakley's....They are pretty good sunglasses too, but way overpriced and I don't like them as well as I like these. These are awesome for driving and being on or near the water, or just about anything else you can think of. One thing I don't know about is impact resistance. It says they are, but I'm not sure how much until I get smacked in the face with something, which I'd rather not happen anyway. Get 'em before the manufacturers price begins to climb.

I really like that KK provides proper care instructions to keep the lenses in top shape. People don’t give any thought how to properly clean these types of lenses and wonder why the coating gets ruined or comes off. Nice touch to include some do’s and dont’s for those who care. The glasses feel great and are super light. I love my Ray Bans but the weight gets bothersome before long. These can be worn comfortably for a long time. I have a few sunglasses from KK with different color lenses and the lenses they use continue to be of great quality and clarity. These will definitely be my go to pair for fishing in the Florida sun.

Great value for the price. They fit comfortably and they block out a good amount of side light. Held up well using in saltwater. Would definitely recommend!

I like these sunglasses. For now, it's winter and they do a good job at protecting my eyes from the winter/snow glare. I have several pairs of Kast King sunglesses, and all held up pretty well over time(I used them for fishing, driving, hiking, walking). This seems to be same quality as my other ones. I also like their soft case, I use that many times when I go on trips to store them and prevent scratching(the hard one takes too much space sometimes).
