Sunglasses

Choose the lens according to where you run — a lighter tint is enough for the forest and cloudy weather, for open landscapes and snow you want a darker one. More important than the tint is the fit, however: the sunglasses must not slip when your foot strikes the ground, so look for anti-slip nose pads and a lightweight frame. Fogging is reduced by ventilation channels and the distance of the lens from your face; a single-piece lens without ventilation will almost always fog up on a hill. Try them on with a hat and a visor, which often change the fit.
