The Racing Jacket is the reincarnation of the classic Jawbone, with a few added perks. These shades crave chaos, and the ear pieces feature a small hole for removable retainer strap. Just in case you want to customize your color combinations, the Oakley "O" icons are now interchangeable, with the help of a paperclip. Count on the carry-over of Switchlock technology, which uses a quick-release lower jaw that opens for fast, easy lens replacement, then closes to lock the lens securely in place. This revolutionary frame architecture creates a suspension system for your lenses. They virtually float around the orbital space, isolated from compressive stresses for maximum optical clarity, comfort and fit. Two sets of lenses are included, Fire Iridium for bright light and persimmon for low light, and you'll have High Definition Optics® (HDO®) to go along with the performance comfort and protection of ultra-premium sport eyewear. Includes Soft Cault case, retainer strap, and soft lens cloth.
