What are you doing standing at the edge of the woods' It's a beautiful day and you're wearing your Smith Edgewood Sunglasses go for that hike you've been meaning to take. The carbonic TLT lens corrects light distortion, so you get the best optical clarity possible. The Evolve frame is made from 53% bio based material and gives you a comfortable fit the whole length of your traipse through the woods. The straight browline shape gives you a look that's heavy on attitude without being heavy on your face. And the auto lock hinges keep these sunglasses in place, just in case that brown bear you didn't see chases you back down the trail.
