More expensive MTB sunglasses tend to have more features, such as easy-to-change lenses, plus an adjustable fit for the nose and arms. The quality and clarity of the lenses will also increase with the price. Better lenses will improve clarity and reduce visual distortion.

Many high-end mountain bike glasses now have photosensitive photochromic lenses, which have a special coating that reacts to light.

This means you can use a lens on very bright days and cloudy days, but even the best ones take a little time to react, while the cheaper ones may take a little longer.

Now that you've got the basics down, here are the best mountain bike sunglasses we've tested recently.

Best sunglasses for mountain biking

100%S3

With a variety of lens colors to choose from, the S3s in the test had HiPER red mirror lenses, which we found to be very versatile and covered a wide range of lighting conditions.

With impressive clarity and popularity, it's undoubtedly one of the best mountain biking sunglasses we've tested. The coverage is extensive, and the frame is still outside our peripheral vision.

The glasses are also very comfortable and stay firmly in place no matter where you're riding. Our helmets have no compatibility issues and include a clear lens.

This pair of glasses didn't get full marks because they didn't have the best lens ventilation (but we didn't steam them hot). The bridge of the nose is a fragile connection, and you also have to pay for the performance.
