The XLJ version of our HALF JACKET frame offers extended lens coverage for larger faces or for those who prefer an expanded field of view. This unique eyewear lets you adapt instantly to any light condition. When the sun fades or flares, switch to a new set of optional lenses and change your entire point of view. Or just enjoy the freedom to customize your look instantly. All Oakley lenses are tested to meet ANSI high velocity and high impact standards. However, please note that only the Industrial M-Frame and SI M-Frame are marked with ANSI Z87.1-2003. Thus, while all other Oakley styles surpass these standards, we cannot endorse them as industrial safety glasses as they are not marked.
