You may remember a post I wrote last spring about sunglasses and how different tint types are better for different activities. The new interchangeable lens sunglasses from Smith Interlock allow you to have them all. There are a variety of frames to choose from and 14 different lens tints including polarized versions which pop in and out. Both come with a lifetime guaranty.

Frames from $139, Lenses from $20 Smith Interlock
