Since the 1980s, Oakley has been providing U.S. troops with military gear and boots. Best known for its popular eyewear, it has spent millions on developing products for those in the armed forces. This partnership was formed to develop new technologies that improve the safety and performance of soldiers. Over time, Oakley's military line has transformed from a few models to a highly specialized division within the company. At its research facility in California, the company constantly works on new innovations. Some items are not available in retail stores, but luckily a number of military items can be purchased through public outlets.
