If you follow baseball, you might recognize the Nike Show X2 Sunglasses on superstars Mark Teixeira and Evan Longoria. That's because they have precise optics for outstanding vision, interchangeable lenses to prepare you for any lighting conditions, and a comfortable and secure fit that makes them perfect for any sport, from baseball and bicycling to tennis and skiing. A little more squared off than the X1, the X2 combines top shelf sport performance with streetwise style. Max Optics lenses have a patented design that has zero distortion from straight ahead and minimal distortion across the entire curve of the lens, because sport doesn't happen in a straight line. A second included pair of lenses keeps you prepared for unexpected storms or sudden breaks in the clouds on a overcast day so you're always ready. The adjustable rubber nose bridge and Secure Wrap temples provide a comfy and secure fit to keep you shades where you want them without creating painful pressure points.
