Chase down farther distances and new personal bests with the help of the Gargoyles Pursuit Sunglasses. These sleek, lightweight shades offer crystal clear vision and ample coverage to help you stay focused on the next horizon. The lenses are engineered to provide sharp contrasts and accurate depth perception for clear, undistorted vision, and they're so tough and precise that even the US military trusts them for use in combat situations. An oleophobic coating on the lenses repels water and oil and resists smudges to keep your line of sight clear. The TR 90 NZZ frame is over 11 times stronger than the standard TR 90 material you find in other sunglasses, so you don't have to worry if you drop them or take a spill, and nose and ear pads keep your shades from slipping when you're working up a serious sweat.
