Oakley SI Standard Issue Fuel Cell Flag Collection Sunglasses Matte Black w/Prizm Grey Polarized. 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. Weve Been Toying with a Mix of Art and Technology for Some Time. The Idea Was to Create Clean Authentic Style for Those Who DonT Just Walk the Path of Life they Stomp It and Leave Footprints. Thats What Led to Oakley Fuel Cell.
