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. 👍

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!

The media could not be loaded. 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.

Light weight, great light deflection, incredible price vs the big brand names. I'll likely grab another pair for my other car!

Do yourself a favor and order these sunglasses. I have paid $170+ for Smith sunglasses with worse quality control than these $30 bad boys. I ordered the gold mirror and silver mirror. Both are great. Ordering another silver mirror just to keep on the boat. If you fish inland, the silver mirror is the clear choice. Blocks enough light so that your eyes aren’t fatigued but lets in plenty of light to still see clearly! I’ve worn them driving around at dawn just because I forgot to take them off. Great glasses! Also, not too nerdy looking like most fishing glasses are. Didn’t attach a picture because it doesn’t do them justice. Just order ‘em!

They don’t quite keep the sun out of your eyes as good as a name brand pair like Coastas. But you pay for what you get.

I got my sleek glasses for around $30 or so. Fabulous deal. I think these are normally used by fishermen, but I absolutely love these shades! They come in a cool case with a microfiber cloth. Whenever I wear them I feel invincible. People look at me differently. They have these striking mirror lenses and are a blue silver. Perfect for blocking out bright lights. There's a bold glitz to them in style. Very happy with these sunglasses.
