F15Edocwrote a review of Smith Serpico Polarized Sunglasses on November 25, 2010
These are the best, highest quality polarized shades I've ever worn. The fit is terrific and comfortable on my large-size face (I'm 6'6"). There are only two caveats. First, they come only with a soft case (no hard case as mentioned in earlier reviews). Second, the stems can scratch the inside of the lens if you're not VERY careful, which is quite annoying. This happens with any compression, even placing in a coat pocket. So, the shades are great for using in the car, but I wouldn't recommend active or trail use.
BTW, Backcountry shipped to Afghanistan with no problems - love it.
