The Oakley Juliet Sunglasses are constructed with flex couplers to allow this 25-piece blend of X Metal and art to fit naturally around the skull. The adjustable frame includes temple shocks, interchangeable nosebombs, and all the innovations that sculptural physics can offer. I majored in sculptural physics in college, and let me tell ya, its no cake walk. These are some quality shades here folks. CLICK THE SIZING/INFO CHART BELOW FOR LENS TINT DESCRIPTIONS.
