KastKing Alanta Polarized Sport Sunglasses Review

KastKing Alanta Polarized Sport Sunglasses

We picked the KastKing Alanta Polarized Sport Sunglasses as the best sunglasses for women due to their special build that includes Grilamid frame, polarized frame, UV protection, e-slip nose, and temple pads. We genuinely praise these features which are found in an eyewear that is worth less than 30 bucks. Although,  we discovered that its UV protection only prevents two types of rays, and that does not include UVC.

Let’s further discuss the features and performance of this eyewear based on the following topics: frame build, lens quality, eye protection, comfort, case quality, and value for money. Keep reading our review to know whether this equipment is good for you or not.


When you venture out into the wilderness for a hike, it’s important to arm yourself with items that will protect you from the elements.

Frame Build

One of the most durable eyewear we have discovered is the Alanta Polarized Sport Sunglasses by KastKing. With its frame coated with reliable and sturdy materials, you won’t have to worry when engaging in physical activities.

KastKing has fortified the Alanta with a Grilamid frame. This type of frame is mainly created for sports, as it can resist impact, is lightweight, and can endure cracks or wearing out. So if you wonder if this can withstand tough situations, the features say it all.

Additionally, Grilamid is a material that is also used in the military and medical field. That makes the frame really sturdy, although flexible. We also recommend its shape and nose pad that makes the eyewear own a good grip in any given situation.

The frame’s finish of the Alanta is covered with glossy elements. From hikers’ perspective, it has an outstanding performance and laudable design that makes them comfortable to wear.

Lens Quality

We can say that the Alanta also stand out in this area. The lenses have the attributes that you are probably looking for, which the Oakley Flak 2.0 XL lack. Alanta’s lenses are indeed polarized which makes these sunglasses excel some more, as polarized glasses lessen the glare in lenses.

KastKing made the Alanta’s lenses with German and Japanese raw materials. Apart from being polarized, they’re also 1-mm thick, and 63.2-mm wide.

Also, the Triacetate lenses passed a double decentering test to guarantee the prevention of visual distortion. This feature has topped the standards of other eyeglasses that fail to provide great quality lenses. With the Alanta, you can trust the performance of both the frame and lenses.

We recommend this pair to users who tend to go on adventures that put them in hot weather situations, as the sunglasses can protect their eyes from possible reflections. Not all sunglasses have this feature, so you’d better ask the seller or manufacturer about it before you buy a pair.


Eye Protection

Similar to other sunglasses, the Alanta possesses UV rays protection. However, we can attest that this feature cannot provide a full protection under a sunny day’s circumstances. If you are looking for a complete protection, then the Oakley Flak 2.0 XL can give you that.

The Alanta can entirely block the UVA and UVB rays, but the Flak can defend your eyes from both types of rays, plus UVC, which is one of the most harmful types. We came to the conclusion that the Flak provides a better performance in this area. Nonetheless, it does not mean that the lacking factors diminish Alanta’s features.

We also like the smoke lenses on the Alanta, as they lessen the brightness coming from the sun. They dim your visuals to prevent the light from hampering your sight. KastKing made several types of lenses available to better suit your needs.

We noticed that the Alanta help see properly under bright sunny weather. This advantage can avoid accidents, especially if you are traveling to unpredictable ground surfaces of terrains.


When hiking, you will be exposed to bright and sunny weather. Therefore, you will need a pair of sunglasses to protect your eyes. These can prevent eye damages and let you see properly. For more information, read our article to know why you need sunglasses when hiking



KastKing has engineered the e-slip nose and temple pads to strengthen Alanta’s grip. Just like on the Flak, these can properly grasp your face, without providing any discomfort. This is especially perfect for different adventures—whether it be biking, fishing, running, or any challenging activities you plan to engage in.

The nose and temple pads are both made with rubber. It is not just covered with it; the material is actually co-injected in the parts to furnish safety and comfort when used even throughout an extended period of time. The texture is smooth, with a sticky quality that adds to the good grip of the Alanta.

It is one of the best options to partner with your activities because it won’t give you pain nor any discomfort in the middle of your activities.


Case Quality

Unlike the Flak, KastKing has created a customized hard case to protect the Alanta. If you check our review about the Flak, you’ll learn that it comes with a soft case. Although it can protect your eyewear, sheltering it with a hardcover is much more reliable.

The Alanta comes with a rigid protective case, and a Prym1 camo microfiber pouch. If you store them inside the case and place them in your backpack, you won’t have to be anxious because of the solid body. You can put them anywhere, just be sure that the case will absolutely cover your sunglasses to prevent breakage.

Finally, the microfiber pouch has a dual function. You can store your glasses inside, or use it for cleaning them. The manufacturer recommends cleaning the lenses with a microfiber cloth and warm water to prevent scratches and damages. Be careful not to immerse them in saltwater, or wiping them with a paper towel.


Just like any other equipment, you need to properly take care of your sunglasses to make them last longer. It’s easy to damage your sunglasses by using the wrong cleaning technique or a strong cleaning solution which is why we recommend that you follow our guide to know the best way to clean and protect your sunglasses


Value for Money

The Alanta has exceeded our expectations based on its price. The features are excellent for these sunglasses, which are cheaper than other brands yet surpass the performance of expensive eyewear.
