Love 'em

  • Familiarity: I've put it through the wringer
  • Fit: True to size

These are my active pair of Kaenons (cycling, hiking, etc.). I wrote a bigger review on the Miramars but Kaenons are great glasses. I have a really big head and these fit well. I've owned them over a year and am extremely happy.

silly name, serious sunnies

    I'll come right out and say it: the Hard Kore is not the most cleverly named, and it certainly lacks some of the refined sculpting and frame design that I've come to expect from sunnies at this price point. It even almost feels dated in both of those respects. However, there's something about the Hard Kore (ugh) that still feels refreshingly utilitarian -- a timeless sport-performance profile, if you will. It's pretty clear that Kaenon is putting all their eggs in the basket of optical performance, and luckily their SR-91 lenses deliver in spades. For me, having a contrast-enhancing lens that protects and cuts glare on sunny days but delivers perfect clarity on cloudy days is a huge win -- the C12 (copper, 12% light transmission) is the ultimate in all-day, all-sport versatility. Plus, its mirrored finish looks absolutely badass. No complaints on the fit or wearability - it's definitely a large wrap frame with beefy arms and big lenses. The rubber nose pieces and long rubber temple tips are more than adequate to keep things snug. Still, if you have a smaller mug, or just prefer smaller sunnies for sport, check out the also unfortunately named Soft Kore.

    * made in Italy, if you're into that sort of thing

    Favorite Sunglasses

      These glasses have replaced my Maui Jim's and Oakleys. They have better lenses and are more comfortable to wear. I use them for outdoor sports and casual wear.

      Really Enjoying the Kaenon's

        Bought the Kaenon Hard Kore sunglasses mainly for running. These are lightweight and have crystal clear lenses. The frames block the light from the side very well. I also like the fact there is no frame on the bottom of the lenses. This really opens up the field of view. I have the C12 lenses and find them a nice all-purpose lens. I had the C28 lenses and found they were not quite dark enough in normal sunny conditions. Would also recommend these glasses for biking, golf, or pretty much any sports activity.

        Love the Kaenon Hard Kore Sunglasses

          These sunglasses are great. I got the copper lenses and they are superb, especially for partly cloudy days. They have quickly replaced my Maui Jims as my favorite sunglasses. Great clarity - love those lenses.

              Kaenon Polarized Takes on Park City Point 2 Point MTB Race

              Posted: 08/25/2011 In Category: Outdoor Trade Shows / Events

              Industry News Release Written By: Tyler Weaver

              Newport Beach, CA — August 25, 2011 — Kaenon Polarized is an official sponsor of the 2011 Park City Point 2 Point mountain bike race. Additionally, Kaenon Polarized sponsored rider, Alex Grant, the winner of the event the past two years, and fellow team rider Marshall Eames, will compete in the 78-mile event on September 3, that will travel between The Canyons, Park City Mountain Resort and Deer Valley. Never crossing the same section of trail twice, the course rises over 14,000 feet, pushing athletes to their physical limits.

              “The Point 2 Point is unique in that it is almost all single-track,” said Grant. “That makes for a tough day in the saddle because you need to be mentally focused the whole time in order to navigate the technical terrain.”

              Proper eyewear is a necessity as riders traverse the course. Alex Grant and Marshall Eames wear Kaenon Polarized sunglasses due to the superior optical clarity and protection offered by the patented SR-91 polarized lenses. Preferred by most mountain bikers, the Copper 28 and 50 lens tints (allowing 28% and 50% of essential light to the eye) let riders tune their vision depending on light conditions. Kaenon's collection of Kore Performance sunglasses are the perfect choice for biking in any condition, reducing eye fatigue when riding in and out of shadows, protecting against plants and debris, enhancing contrast when riding on trails, and allowing for increased visual awareness at high speeds.

              “Riding single-track for seven hours without stopping requires a lot of focused vision,” said Grant. “You need your eyes to be protected and relaxed rather than strained. Kaenon's ultra-efficient polarized lens does that better than any other lens out there.”

              About Kaenon Polarized
              Since 2001, Kaenon Polarized has continued in its mission to provide elite athletes and active lifestyle enthusiasts with unmatched polarized optics and high-performance frames, all with superior fit and luxurious style. With proprietary and revolutionary SR-91 polarized lenses, Kaenon Polarized continues to push the boundaries of active optics with award-winning performance sunglass styles, all available in Single Vision and Freestyle Progressive prescription.

              Great Biking Glassses

                I have used the Hard Kore sunglasses for a few seasons as my main biking sunglasses. They breath well and have no frame on the bottom which allows excellent visibility for cycling. These shades stay on well and are comfortable.

                Bottom line: Great biking shades that I highly recommend.

                do you do Rx lenses? If not, then where?...

                do you do Rx lenses? If not, then where? I live in Los Gatos CA.

                I don't believe that sells these in Rx lenses, but they are available.

                My New Favorites

                  After 10 years in several pairs of Maui Jims, I purchased a pair of Hard Kore G12's. The clarity is amazing and the frames are lightweight and comfortable. The gray tint doesn't overdim your vision and in fact, you forget you are wearing them. These are easily my favorite sunglasses.

                  Nice, but large

                    I have a skinny head (6-7/8) and these are way to big for my head that I had to return them. They did look pretty cool, but I could put my thumb between my temple and the glasses they were so wide. If you're someone that has a problem like myself don't get these glasses and go get some polarized Arnettes for half the price.

                    I have tried the C12 lense and like it. ...

                    I have tried the C12 lense and like it. Someone has suggested I might like the G28 better for all arround use. Any one have experience with these lenses?


                    I've used them. They are definitely "brighter," but they still reduce glare like you'd expect from Kaenon's lenses. On cloudy days I prefer G28, but sometimes I'll also wear them during bright sunny days, especially during non-mid-day activities when the sun isn't as intense. They've worked great for me. Hope that helps!

                    Killer shades

                      These are fantastic sunglasses. The SR-91 lenses are crystal clear, and the polarization is excellent. These are great glasses when polarization is a must (flyfishing, being on the water or snow, or driving on wet roads).

                      I own the Hard Kore and also the Kore, and I find myself wearing the Hard Kore more often. The Kore are also great sunglasses, but the lens is bigger. While the bigger lens does a slightly better job of blocking light reflecting from below, they also have less air circulation, and are more prone to fog up. The Hard Kore, OTOH, allows a little better air flow, yet still provides excellent coverage. But by no means is the Hard Kore a small or narrow lens; actually, it's closer to the size of other "normal" shades. As should be evident by the picture, these shades do a great job of blocking lateral light, yet they are much lighter than they appear. Of my (too many) sunglasses, these are hands-down my favorites.


                        Functional and fashionable frame - the first 'shield' style that you can wear on and OFF the bike. Cool looking and amazing optics. You can't find better lenses than these - worth every penny and then some. *also does NOT scratch easily at all so don't fret about wearing a high end sunglass on the bike!!!!

                        Hi, I wear perscription glasses, can I...

                        Hi, I wear perscription glasses, can I order the same per. for your glasses?

                        Hi John. Kaenon does make SR-91 prescription lenses, but my understanding is that you can't order them directly (from or even from Kaenon), but instead you can get them through some eye doctors. More information can be found here:
