The word Oakley is synonymous with top quality sunglasses and they have built a good reputation for quality. The Oakley Flak 2.0 Xl OO9188 Sunglasses are some of the best that we could find they come with a semi-rimless design that will definitely add to the aesthetic appeal that the name Oakley already does on its own. Constructed with a durable plastic O-Frame, the sunglasses are capable of taking a beating from nature and features a large size that will fit most people.

Since it is lightweight, the glasses can actually be worn for an entire day and they won’t bog you down. With polarized iridium or PRIZM technology added depending on your needs, the glasses actually offer you 100% UV protection. While the glasses are constantly being improved by Oakley, they do have a slim fit and might not be ideal for every sporting occasion. The upside is that they will actually stick to your face and you won’t need to worry about them falling from your face.

This makes them perfect for all action sports, including mountain biking. Oakley is one of the more expensive brands and this could potentially dissuade many buyers. However, the design of these glasses are durable and many people swear by Oakley optics when it comes to the best.

We would highly recommend them if you have the funds and they should last you a couple of years as well.

Upon first inspection, you might be tempted to think that these glasses have been designed for skiers. However, the Bolle B-Rock Sunglasses does not only look durable, but they are durable with full frame construction. The full frame will add more strength to the lenses for when you need to constantly deal with gravel popping up.

For the glasses themselves, you will notice that they offer a lot of protection to the rider and this includes padding on the inside that will cover your brow. It not only makes it more comfortable but reduces some of the sweat that could buildup on your forehead. The active design also means more comfort and the glasses won’t fall off as easily.

Another one of the top features is that these glasses can actually be used in all conditions. Since they will reduce the amount of fog that will build up, you won’t need to constantly stop to clean them. They won’t reflect either, making them ideal for when riding in a group situation, while the hydrophobic coating will keep them clean.

Unfortunately, all of this technology does come at a price and you will need to understand that these glasses are rather expensive. However, they are not only designed for mountain biking and is commonly used for many adventure sports.

We would recommend them for the versatility and some of the features that might outshine Oakley.

Key Features To Consider When Choosing Sunglasses For Mountain Biking

As we have done a ton of research to pinpoint which of the options are the best, we have decided to share some of the key features with you. These features might not relate to all sunglasses, but more specifically for action sports.

If you are looking for a new pair of sunglasses to go mountain biking with, we would definitely suggest that you keep the following features in mind:

Lens Contrast

For a mountain bike rider riding against the sun, the lens contrast is one of the most important things to keep in mind. The better contrast you have with your lenses, the clearer, you will be able to see the road and all the obstacles in your way. High-contrast lenses might be a little more expensive, but they offer greater detail of what lies ahead.


The glasses definitely need to have a comfortable fit and this is why brands are designing them to be ergonomic. This means they comfortably fit around your face without having to constantly be readjusted. Unfortunately, you need to look at the size of the glasses as well and we have had instances of the glasses being a little too small for most people.


Gravel and other dirt might be a barrier to your success and when you are riding in terrains that offer a lot of gravel, you might want to invest in glasses that offer more coverage. The larger area covered, the less time you need to spend dodging gravel. When looking for the mountain bike sunglasses, we always believe that bigger could be better.


Once you have done all the comfort and protection feature research, the look is just as important. No one wants glasses that look cheap and old-fashioned. It is important to find the right look that not only fits your face but your style as well (check out this article for a general guide on which style of glasses fit which face shape). Fortunately, most brands have designed the glasses to look great and feel great at the same time.


Since these sunglasses can be a little expensive, you need to look for a decent warranty that will keep you protected. You might have noticed that sunglasses are easily reproduced and sold as the real thing. However, they won’t come with a warranty. Choosing a reputable supplier with a reputable brand is really important to ensure you get what you paid for.


Now that you have seen all the important features and many of the best rated mountain bike sunglasses, we hope that you have found a set that will work for you. Oakley stands out as one of the leading brands and they have been an industry professional for years now. All of the Oakley sunglasses in this list should make a difference to your mountain bike experience.

We would like to thank you for reading this article and encourage you to share some of your thoughts. It is no secret that there are many other mountain bike sunglasses and brands on the market today and we would love to see which of them you favor.
