Tifosi Rail XC Fototec is called Runner's World's photochromic winter running sunglasses of choice. The lenses stay almost clear on gray, overcast days, then darken as the light comes up, so your eyes are covered in all kinds of winter conditions. The lightweight frames add to the comfort, so they’re easy to forget you’re even wearing them. Check out Rail for a smaller version.
