Just recently Smith Optics have partnered up with Commute By Bike. They sent us the Theory and Threshold to review.

What I like about Smith is that they offer a Limited Lifetime Warranty and a boat load of products to fit your needs. Not only that, but they sponsor some of the biggest names in the sport of cycling: Eric Carter, Jared Rando , Tara Llanes and Steve Peat just to name a few.
Check them out!
