Oakley Jawbreaker sunglasses are probably one of the most iconic modern cycling accessories. Being the choice of professional riders worldwide, the Oakley Jawbreakers are built for pure performance. Thanks to the HDO™ technology and advanced Prizm lens technology, these glasses offer maximised colour contrast as well as enhanced image quality and visibility out on the road. With Switchlock™ technology built into these glasses, riders can transfer replacement, photochromatic and prescription lenses into these glasses with ease. To increase ventilation, Oakley has even fitted the Jawbreakers with vents to reduce steam build up in the warmest conditions. While the O-Matter™ frame ensures these glasses are durable and lightweight, the temples can be exchanged so you can find the perfect fit for you and your helmet. With Unobtanium ® ear socks and nose pads, Oakley has ensured that these glasses stay firmly in place, even when sweating.
