Thinner, lighter, better

As far as iconic sunglasses go, few styles have had the sort of cultural impact as Rayban's Wayfarer.  We've seen many updates and variations of the original shape through the years, the newest of which is Liteforce Wayfarer Tech.  As Rayban puts it, the new high-tech plastic "provides superior lightness, durability, flexibility, and comfort," and after wearing them around the office for a bit, I have to say that  they really are pretty awesome.  Check them out below in blue and grey.
