I do a lot of sailboat racing and these are hands down the best polarized lenses I've ever had. I've used Revo, Maui Jim, Ray-Ban, Smith, Bolle, and others, but the Kaenons cannot be beat for clarity and glare reduction. They really help me see the wind on the water. I use the Copper-28 lenses, which are a very good all around lens. They block enough light for really bright days, but are light enough to use on cloudy or hazy days. If you do watersports, you will be very happy with these glasses.

These are the clearest, most comfortable glasses I have ever had. I own 7 pairs too -- everything from Maui Jim to Costa Del Mar's. Nothing compares.

The Kore is raw performance. Light weight frame, lens sizes for perfect fit, lens tints for optimum performance. I own the Kore Medium C28 and I bike in this frame all the time in all light conditions. Best lens I've ever worn - it is incredible.

I've used several polarized lenses over the years and most of them aren't suitable for mountain or road riding. Though the value of a polarized lenses is most often derived on water or snow, it's great to have reduced glare in all conditions. That said, the Kaenon Kore sunglasses are the only polarized sunglasses I recommend for road or mountain biking. With others, you'll get rainbow splotches as your tearing up the singletrack downhill (not too safe), but with Kaenon's lens technology, you get the clearest vision and best protection available.

Sure, polarized shades are nice for driving (to cut the glare off of the road). But to use Kaenon Kore's for just driving would be like using your Porsche (assuming you have one, which I certainly don't) just for trips to the corner store. No, I really *need* good polarization when I'm sight-fishing for trout, on the snow, or driving on wet roads. Since polarization is so important for fly-fishing, I've gone through polarized shades from Oakley, Maui Jim, Smith, Bolle, Costa Del Mar, Action Optics, etc. And none of these work as well as my Kores (C12) in terms of clarity, comfort, and coverage (i.e., no light gets in around the lenses, and they don't block my field of vision). Yes, they give a little of a "bug-eye" look, but their performance can't be beat! I even like them so much that I picked up another pair with the Y35 lens, and these work great for low-light conditions (before sunrise or after sunset, or on very cloudy days).

If I had to come up with one complaint, it would be that the fit and coverage are so good that air flow is reduced, and these sunglasses can fog up if I'm involved in very aerobic activities. I also have a pair of Hard Kores that I often wear when I'm putting off heat. The Hard Kore is also an excellent pair of shades, but the lens is somewhat smaller (but not small). Which ever one you choose, Kaenon polarized sunglasses are some of the best shades you will ever find.

I work outdoors about 6 days a week and my Kore's are the only pair of sunglasses that I can wear all day long(I also own Arnette, Maui Jim and Hobie too). They are very comfortable and do stay put for the most part. Clarity is excellent and the polarization(blk-12 lens) keeps my sensitive eyes from squinting. The only problem I've had w/ the sunglasses is that both ear pads slide off. It's not really a problem if I don't take them off constantly. I purchased them from a friend for cheap, so I can't really complaint. Kaenon puts out a nice product. I also own 2 pairs of Kaenon Rhinos.
