The Interlock Trace sunglasses' strong, flexible frame is perfect for year-round bike riding, rigorous backcountry hikes or simply for casual wear. And, the comfortable temple pads won't create a brain-squeeze. The rectangular lens shape is designed for maximum eye protection and utilizes Smith's Tapered Lens Technology for zero distortion. Medium fit frames are available in black or brown and come with three sets of Polarized TLT Carbonic lenses in brown, rose and clear mirror. A sturdy, crush-resistant case is included.

The SMITH Interlock System
At last there's an easier way to adapt your sunglasses to those ever-changing light conditions. Smith's new INTERLOCK Interchange system makes switching out lenses a breeze. Just twist the Interlock temple arm to open the front of the frame, switch lenses, and twist the arm back for a secure close.
