Nike Siege 2 is such a versatile pair of sports sunglasses, used by professional athletes, cyclists and golfers.
Siege 2 has adjustable secure-wrap temples and an adjustable ventilated nose bridge. The lens design, like the bridge, helps reduce fogging and Siege 2 lenses are fully interchangeable to match any condition. A spare set of lenses is included in each of these models and one of these is Nike Maxadapt, a photochromic lens which darkens and lightens according to the light conditions.
