Lightweight frame. Wrap-around polarized lenses. Slip-resistant nose and ear pads. Those were the top criteria when I started my search for new, active sunglasses. And I found it all in the Parallel 2 from Smith, plus the great added feature of being able to swap out lenses for low-light conditions. Mountain biking, trail running, or walking downtown, these are the glasses I’ll be wearing. Available at Dan Bailey's; $139.
