Why we like it:These adjustable shades have a fuss-free lens changing mechanism.
Lens changing: Idiot-proof: Just pull the lens downward from the outer corner. Slide the new lens into the groove and snap it back into the same corner. We love the lack of switches, levers, and bending plastic.
Fit: The angles in the temples reduce bounce and slippage during high-output activities. They wrap around the face snugly (8 base curve), and hook around the ears, without adding pressure. “They stayed in place, even when I was bounding down a mountainside on a trail run down Colorado’s Mt. Audubon,” one tester says.
