Oakley MTB Sunglasses Features
Frame Technology
Oakley's proprietary O Matter™ frame material is used in all Oakley sport sunglasses, including the MTB frames on this list. This nylon-based material is extremely lightweight, but also incredibly durable. Falling off your mountain bike comes with the territory. Knowing that you have an impact-resistant frame means you have one less thing to worry about.
Lens Technology
When it comes to sunglass lens tech, PRIZM™ is second to none. This contrast-enhancing lens technology makes details easier to see. PRIZM™ Trail and PRIZM™ Trail Torch are specifically designed for trail environments. Both lenses boost the colors your eyes are more sensitive to so you can easily spot changes in terrain. This makes for a safer and more enjoyable riding experience. See how both lenses compare in our PRIZM Trail vs. PRIZM Trail Torch Review.
