|| The Oakley Wind Jacket(TM) sunglasses are engineered for high-velocity living. With snap-in eye gaskets and 2 sets of interchangeable lenses, you can adjust to whatever life casts your way. For easy lens swapping, Switchlock(TM) lens removal system relieves distortion-causing frame pressure by allowing the bottom part of the frame to pivot open. Quick-release removal system minimizes lens handling, so dirty fingers need not touch lenses; cam lock frame closure securely holds lenses in place. Attach the eye gaskets in especially windy conditions, or leave them off for a more traditional sunglass look. O Matter(R) nylon frames are lightweight, stress resistant and flexible for long-term wear. Polycarbonate lenses are optically correct, shatterproof and scratch-resistant. Oakley permanent lens coating sheds sweat, rain, dust and skin oils, preventing build-up and keeping your vision clear. Backs of lenses are treated with an antifog treatment to minimize moisture buildup. Unique Oakley 3-point fit includes optical alignment for sharp, accurate vision, impact absorption for improved protection, and geometry designed to enhance peripheral view. Matte black frames come with warm gray lenses for maintaining color recognition in bright light; interchangeable clear lenses offer protection in low-light conditions. Nose pads and stem sleeves are hydrophilic rubber that becomes tackier as you perspire, holding eyewear in place as you move. Oakley Wind Jacket sunglasses feature relatively high 8.75 base-curve lens geometry that optimizes peripheral vision and side coverage.
