I got my clk's beginning of last season. Compared to other goggles in the same price range, i got 3 lenses(1 being polarized) and a very nice case to store lenses in. Other companies offered 2 lenses and no case. Ive had 50+ uses out of them. Not a single fogging issue. They fit great w/ my bern Watts helmet.
My only complaint is the polarized lenses don't go in and out very easily. The other 2 go in and out like butter. And i was worried i would scratch the lenses w/ the way the case holds lenses. But only scratches i have are from branches.
