See and be seen in Enigma Mass, a bold style designed to grab attention through structural artistry and dramatic edge. With a nod to Oakley’s heritage, the shape of each temple was inspired by the signature sunglass trigger stem design. This full-rim frame is made from lightweight O Matter™ and lightweight C-5® temples that taper from thick to thin. TruBridge Sport Unobtainium® nosepads keep the frame firmly in place while Unobtainium® earsocks provide a no-slip grip.
