The Oakley Jawbreaker Prizm is the ultimate in both performance and design. Yet the development of the Oakley Jawbreaker was just a coincidence. During a casual dinner between Marc Cavendish and Oakley's design team, it came up that 'Cav' wanted a new type of glasses. He wanted the protection and fit of a Racing Jacket in combination with the lens type and all the other comforts of a Radarlock. Oakley got started on this, and after many designs and tests the Jawbreaker came out. Glasses that focus on improving and enlarging your field of vision/ventilation in combination with maximum safety. This combined with the best features of the Racing Jacket and Radarlock results in the ultimate in cycling glasses.
