Had a few rides out with them in variable light conditions and have to say they perform perfectly, lens is good. Like the styling. Great face coverage. Would highly recommend. Really happy with the purchase. Fast service from Scicon.

Product review from pezcyclingnews.com:

When the Scicon Kunken arrived I was sure I wouldn’t like them, but once you are wearing them they don’t feel any different. Personally I found two advantages: The lager lens stops any chance of wind getting into your eyes causing you to tear up, a problem I have had on occasions. Also you don’t have any light at the bottom of the glasses, sun reflecting up off the road.

Now that I’m a convert to larger glasses, what about the Scicon Aeroshade Kunken? Very comfortable with help from the adjustable nose piece and legs. Being able to adjust the hight with the nose piece is quite a bonus. They also feel secure on the road. The vents on the side of the lens and at the top of the frame should stop any fogging, not that it was a problem.

Talking of the lens, the Scicon monogram logo pattern on the lens looks great, but of course you can’t see it on the inside. More importantly there is no glare and your view of the road is sharp and clear.

The Kunken comes with the usual cleaner/bag and also a soft case that can also be used as an under the saddle bag. As Chuck Peña always says: “Take you helmet with you when you try glasses.” No problem with my Giro, the Scicon Kunken fit well, no bumping against each other. As you would expect from Scicon, the Kunken are sturdy and well made. Unless a car runs over them, they should see good service for a long time.
