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. 👍

I really enjoy these glasses. They are comfortable to wear, I primarily use these glasses to drive and they aren't to dark and I can see everything.

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!

Initially, I was very impressed with the glasses. And that they came with a soft case, and a hard case. But after wearing them for a few days, I realized the lens quality is pretty bad. They distort your vision and give me bad headaches. Like wearing prescription glasses when you don't need them. Maybe it's just me, and I'm a sensitive sally, but I wish I would have spent a few more dollars and gotten something better quality.

I bought these for my son for Christmas and he loved them. Super stylish and great quality for the price. Came with a soft and harder case.
