The Oakley O Frame 2. 0 Pro XM Goggles are just like your favorite pair of all-mountain skis. They fit that "just right" sweet spot and work for just about all the terrain and conditions you can dream up. Their lenses are durable, protect against harmful UV rays, and provide corrected optics to help you see more clearly as you shred. Their wide frame helps you see more in your peripherals, triple-layer face foam wicks moisture and boosts comfort, and reliable anti-fog coating helps ensure that you won't have cloudy vision when you start skiing hard. Plus, they come with an included pair of secondary lenses that switch out easily when light conditions start to change.
