Best Rimless Running Sunglasses: Tifosi Rail XC
What’s better than a single pair of slick shades? Three for the price of one. The Rail XC is a cycling style with interchangeable lenses, but the rimless shield lens provides a wide-open field of view for runners, too. Each pair comes with a high-contrast reflective lens for bright light, a medium-tint lens for moodier conditions, and a clear lens for low-light protection. You can easily swap them out by twisting on and off the arms and nose pad.
