The Oakley Batwolf sunglasses are about original style, and it's a clean look of authenticity that makes the statement. A single continuous lens sweeps across a comfortably lightweight O-Matter frame. The icons are interchangeable and two sets are included. They stay secure with hidden latches until you're ready to swap them out with a new color. It has a Three-Point Fit that keeps the optics in precise alignment, and it's designed to fit comfortably on medium to large faces. It also meets the uncompromising standards of ANSI Z87.1 for high-velocity and high-mass impact resistance, and the Plutonite lens blocks 100% of all UVA, UVB, UVC and harmful blue light up to 400nm. Clarity is key, and single-lens Oakley designs like this take advantage of POLARIC ELLIPSOID geometry to keep your vision sharp at all angles of view.
