been alternating between a pair of Costa Del Mar Switchfoot (polarized)
and Kaenon Arlo (polarized)
i've used a few pairs of Kaenons and a few pairs of Costa Del Mars and liked the clarity on them. A glass lens set of costas i had got stepped on in a backpack and one lens spidered, i need to see if i can get it replaced. also used smith and oakley and like all those as well. heard great things about maui jims, too.
