Comfort and durability are maintained by earstems of sculptured X Metal® Titanium with unique temple-shock hinges and soft Unobtainium® earsocks for a secure fit. The curves are honed for a more angular design with subtly squared orbitals. Oakley's patented Three-Point Fit retains optics in critical alignment and eliminates the discomfort of ordinary frames that mount with unbalanced pressure points. Never before has this degree of precision achieved this level of comfort.
