Features Technologies Standard Issue Fuel Cell USA Flag Collection Product overview More features Show your pride for the land of the free and the home of the brave. The Matte Black frames of the Flag Collection are highlighted with American flag emblems. They honor the history and heritage of a nation founded on freedom and salute those who protect that freedom. Editions in this collection are available in full color and tonal emblems. Along with High Definition Optics (HDO) we paired this patriotic feel with some of our most popular SI styles, SI Holbrook and SI Fives Squared. We?ve been toying with a mix of art and technology for some time. The idea was to create clean, authentic style for those who don?t just walk the path of life ? they stomp it and leave footprints. That?s what led to Oakley Fuel Cell. FRAME LENSES Size: M (130mm) Sold in one unique size Lens Height 38.8 mm Frame Width 130.33 mm Arm Length 130 mm Lens Width 61 mm Bridge Width 19 mm ?
