Jacob K.wrote a review of Smith Interlock Trace Polarized Sunglasses on May 6, 2009
I really enjoy these glasses. They are comfortably and stay on my face skiing or bending down in the stream. One thing to consider they do have interchangeable lenses, but to buy other polarized replacements can get pricey. I bought the traces with the polarized grey lenses and they don't work great for fly fishing as they are too dark. The photochromic copper replacement lenses are $70.00 retail. So when buying these glasses make sure you get the lenses you want the first time.
