The Klay is a great addition to the Kaenon line up
The Klay is one of the newest styles to the Kaenon style choices - This is going to be one of the best fitting men's pieces if you like the fuller coverage and deeper lens shape. The SR-91 lens is hands down the best lens on the market - as clear as a glass lens and the polarization is incredible - better polarization than any polycarbonate polarized lens out there (the SR-91 lens filters much more glare than other lenses so it is WAY more comfortable to wear). If you are on the fence I'd say go for it - you won't regret it!!!
