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.
