Randall Edwardswrote a review of Smith Parallel Sunglasses - Polarized on August 6, 2010
I must admit, I have never disliked a Smith product. The optics are among the best, and the warranty can't be beat. That said - I got these lenses through a warranty of an old pair, from which that the polarized covering had de-laminated.
On to the shades -- they're pretty lightweight, and they don't move around on my face. I don't know if the included lenses (clear and rose) will get much play, but they could be good if I'm biking at night. These are good for an all around pair of sport glasses that will stay on your head and block the sun, while providing an excellent field of view.
