The Oakley Industrial Tombstone Spoil has revolutionized the shooting eyeshield. Oakley engineers worked alongside top marksmen in order to best identify the issues they had with current shooting frames and see how they could create a frame that would better meet their demands. The Tombstone features an expansive view that is free from any frame obstruction. A single release trigger makes swapping lenses out a breeze. The Tombstone also features Unobtanium nosepads which will keep the frame from sliding down your nose if you break a sweat. And if your'e wondering, these glasses are ANSI Z87.1 rated for impact protection. However, they are not ballistic or mil-spec rated. Get the best clarity and eye protection with the Oakley Industrial Tombstone Spoil.
