Part of Oakley's military-ready Standard Issue series, Oakley SI Ballistic M Frame 3.0 PPE Sunglasses with Gasket surpass ANSI Z87.1 Industrial Standards for high-mass and high-velocity impact protection; they also meet EN166 (EU) safety eyewear standards to help keep your eyes protected in the field, on the range, and beyond. A lightweight and soft rubberized gasket comes pre-installed and designed to fit snugly against the head to help block wind and dust. These Oakley Personal Protective Equipment (PPE) sunglasses boast a single shield-style lens made of pure Plutonite, a proprietary material that offers the highest level of optical clarity available in eyewear. The clear lens features an anti-scratch coating on the front of the lens and a permanent anti-fog coating on the back. It delivers 89% visible light transmittance, suitable for use in low light to no light conditions with no influence to contrast or color. With these Oakley sunglasses, you get razor-sharp clarity at all angles of view, which maximizes peripheral vision and protection against sun, wind, and side impact. The chemical-resistant O Matter frames have thin stems for compatibility with over-ear hearing protection and communication systems, plus an Unobtainium nose pad to ensure a nonslip comfort. Includes electrostatic Microclear bag for cleaning and storage. Manufacturer style #: OO9146.
