The M Frame Hybrid SI for Smaller Sizes
The Oakley M Frame Hybrid S SI Sunglasses is the same design as the Oakley M Frame Hybrid SI. This S SI model is built to give a better fit for smaller or narrower sizes. Replacement lenses are exclusively for M Frame S SI glasses. We offer them in clear, grey, and black iridium.

Bullet Resistant Lenses
The Oakley SI M Frame® surpasses ANSI Z87.1 Industrial Standards for high-mass and high-velocity impact protection. All 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.
