Wear these DAILY as my driving glasses, and will use them for my activities as well.  Seems well built and the shading helps tremendously in bright outdoor settings (ie sitting in LA traffic).  I liked it so much, I bought another one, in a black frame!  I have a larger head so for me, it's tough to find sunglasses that fit, so this is just a tiny bit more snug than I care, but fits well and relatively comfortable over an extended period.  The bridge pads will start to dig into your face, so I do have to adjust it around every once in a while.
