The M Frame Array includes three shields of pure Plutonite. The grey lens controls reflection and transmission, while the clear and VR28 lenses provide optical armor for night and low light shooting. POLARIC ELLIPSOID geometry maintains razor sharp clarity to keep your focus on the bullseye and a low profile nosepiece won’t fragment your field of view.  

The Oakley SI M Frame® included in the array surpasses ANSI Z87.1 Industrial Standards for high-mass and high-velocity impact protection. The lenses are made of pure Plutonite®, a proprietary material that offers the highest level of optical clarity available in eyewear. You get razor-sharp clarity at all angles of view, which maximizes peripheral vision and protection against sun, wind and side impact.
