Sturdy, light, and great, clear coverage.  What more can you ask for in sunglasses?  I broke my $16 discount sunglasses and decided to upgrade to these Smith sunglasses.  What a difference!  Worth every penny.  Compared to my cheap sunglasses, the optics are clear and even, and the fit is right on.  These are the "max" version, so thay dip down a little to give extra coverage.  When I ordered the max, I was concerned that they would be too big.  But they look and feel great.  Comes with a case and two extra lenses (one is rose-ish hue and the the seems to be closer to clear). The case is huge, so you may end up wanting to invest in a sunglass sleeve.  Great shades.
