If it ain’t broke, don’t fix it. That’s the idea with the I/O, Smith’s long-running high-quality goggle. The first of many goggles to feature quick changing lenses—via the top lens toggles—the I/O set the bar in that department. It employs Smith’s spherical Carbonic-X lens that lets your eyes roam the land distortion-free. The Porex filter in the lens pushes out moisture between the dual lenses to keep your goggles from fogging up. And lastly, the strap uses the fan-favorite clip buckle, making equipping and adjusting a breeze.
