Oakley Flak 2.0 XL

Looking for a pair of shades that can defend your eyes from the UV rays? The Oakley Flak 2.0 XL can answer your needs. These flexible sunglasses can protect you from all types of UV rays. They have a good grip, which is reinforced by the 3-point fit system, unobtanium grip, O Matter construction, and semi-rimless design. What we dislike though is the plastic frame and non-polarized lenses, however, some parts are also covered with rubber materials.

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.

Frame Build

Sunglasses’ frames are vulnerable and can break, but you can trust the flexible build of the Oakley Flak 2.0 XL’s frame. We all know that eyewear needs to be taken care of because there are instances where, even with a small accidental collision, the glasses can be damaged easily. Although these sunglasses are made with plastic frames, the manufacturer packed it with elements to make them tensile.

Having a bridge of 12mm, Oakley engineered their unique 3-point fit system to allow the fair allocation of pressure in your face, nose, and ears. This is a great feature for you to avoid constraints on those areas when using the glasses for an extended period of time. The attribute is also strengthened with the pair’s own unobtanium grip, which improves the hold of the sunglasses with the nose pad and temple arms.

The Flak 2.0 are also lightweight thanks to the O Matter construction, and the lenses can be adjusted lower, without interfering with your vision. What we just noticed however is the limit of the bending feature, as they can break if you overdo it, but this applies to all sunglasses. Our overall assessment expresses the sturdiness and compactness of this eyewear.

Lens Quality

In terms of the anti-glare feature of the Flak 2.0, we concluded that it is satisfactory, but not the best. So if we rank this aspect among that of other sunglasses, it won’t sit in first class. It shows a standard performance that you can also experience with other models.

The lenses are made with non-polarized plastic material, which is why the anti-glare feature is weak on these sunglasses. We have gathered the opinions of different users, and what we noticed in their statements is the fragile performance when used over a lengthy period of time around sharp reflections, as it can hurt your eyes.

However, you can upgrade your lenses by switching them for polarized lenses. The lenses are 59-mm wide, with a peak of 37mm. Nonetheless, the downside of these sunglasses is overturned by their sun protection.

We recommend you to first know where you are going to use them because it hugely affects their performance. If you compare these to other sunglasses, we can say that it can be leveled into the normal types.


Eye Protection

The Oakley Flak 2.0 XL have a shape that perfectly fit the user, making the protection dependable since it covers your eyes properly. As for the eyewear’s role, this can shield your eyes from the outside elements that may affect your sight. All in all, if you are looking for exceptional protection, you can list those as the ideal eyewear.

The Flak 2.0 may be weak due to their non-polarized lenses, but we can say it rocks when it comes to UV rays protection. Oakley did impressive work here, as it can completely protect your eyes from all sorts of harmful UV rays, including UVA, UVB, and UVC light.

From what we saw, these have a definite design that follows the structure of the user’s face, but bear in mind that these sunglasses can’t fit all sizes. Some people convey that it is best for average sizes, however, when tested by a person with a larger face, the lenses looked like they were hanging on the lower area.


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



We think that Oakley mostly provides more focus on the comfortable aspects of the Flak 2.0 than in their design—protection and comfortability, to be specific. But what makes us think that they put weight on these features?

Since we have already mentioned the capacity of this model’s UV protection, let’s look into its body build. If you get to visualize the frame, you can witness the rubber components that Oakley installed. The nose piece helps the glasses have a strong grip, even if your face is sweaty and oily under the sun.

The frame is packed with a 3-point fit system, unobtanium grip, O Matter construction, and semi-rimless design, which makes the Flak special. These are the factors that caught our attention as we can’t find them in other sunglasses. We also think the manufacturer molded the sunglasses properly to make you feel at ease, even if you engage in tough physical activities.

This model is one of the best choices if you are a sporty person or like to travel. It is lightweight, sturdy, and pleasant to wear.


Case Quality

As for the case quality, Oakley complements it with a soft case. Now, you might be thinking that it will make the sunglasses unsafe if you place them in your backpack. The answer is no, but make sure to put them on top of your stuff.

The quality can be considered as good, as it protects your sunglasses when packed. Although the case is soft, it is not that bad. And you can still purchase a microfiber bag to thicken the soft case if you want to ensure the protection of your equipment.

Last but not least, beware of how you pack this type of gear as it cannot endure heavy things. Be watchful about where you place or insert them. Even though these are sturdy and flexible sunglasses, they won’t hold long under hefty materials.


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
