No need to compromise—the Oakley Siphon Prizm Sunglasses offer performance you can take on the trail, and style you can take to town when you're done with the day's adventure. They feature the crystal clear contrast of Prizm lenses, the UVA and UVB protection of Plutonite, and the lightweight durability of an O Matter frame. No-slip earsocks and a wrap-around design keep your shades in place whether you're headed for a run or mountain bike ride, while a classic silhouette offers casual style you can wear everyday.
