The Jacket® family has spawned a new breed that maximizes the benefits of Unobtainium®, our hydrophilic material that improves grip with perspiration. The soft synthetic is decked over stress-resistant O Matter® frame material to form grip anchors, nosebombs and earsocks. This achieves a comfortable Three-Point Fit that maintains precise alignment for our patented XYZ Optics®, an advance that extends clarity to the peripheral edge of lenses. Prescription ready.
