Building upon the success of its predecessor, Oakley's Latch Alpha sunglasses were made for those always on the move. Constructed of die-cast aluminum encased in Unobtanium™, these frames feature a bold double bridge and a striking lens shape. The most gripping aspect of the frames? The clip hinge mechanism that enables the wearer to clip the sunglasses securely on any collar, proving these shades really can go anywhere you do. Get hooked on Latch Alpha.
