Sporty yet sophisticated, the men's Oakley Siphon sunglasses feature a high-wrap style that provides a clear field of vision. Oakley's patented O Matter makes up the sculpted full-rim frames, ensuring these shades are light, durable, and impact-resistant. The bayonet temples end with Unobtainium tips for a no-slip grip that works even as you sweat. The brand's signature Three-Point Fit guarantees a well-aligned and comfortable fit by touching only the temples and nose bridge. The rectangular rims of these O Matter Siphon sunglasses define the features of square, oval, and round faces.
