What is the name of Oakley's lightweight frame material?

Oakley’s lightweight frame material is called O Matter.

O Matter is Oakley’s proprietary lightweight frame material, designed to balance low weight with durability, flexibility, and comfort. It is especially associated with the brand’s plastic sport frames, where the material helps create wraparound shapes without making the eyewear excessively heavy.

The name appears as O Matter or O-Matter in Oakley product descriptions, but both forms refer to the same branded frame technology. It should not be confused with Unobtainium, another Oakley material used on components such as nose pads and ear socks. Unobtainium is intended to increase grip, especially when the wearer is sweating; O Matter is the principal frame material in the relevant designs.

O Matter became part of Oakley’s broader identity alongside unusual shapes, high-impact lenses, and sport-specific engineering. The company has used it across sunglasses, goggles, and other eyewear families. “Carbon Fiber,” “Titanium,” and “Aluminum” can appear in selected products or components, but none is the standard answer for Oakley’s signature lightweight frame material.
