We&';re proud to present the first ever BALL-ISTIC(TM) Pit Vipers. A step up from the ANSI Z87+ rating, these pairs can take a .15 Caliber piece of shrapnel at 660ft +/- 10 per second. Yup, they&';re up to U.S. Military Standard Ballistic Rating. Matte rubberized frames, laser etched logo, and toned down non-mirrored lenses make them a safe choice for the field.
