KOOSupernova Sunglasses(Return to Product Page)

I was looking for a lightweight, photochromatic sunglass with a little more coverage than my Julbo's. I settled on these given the Zeiss lense. And while I like the slightly larger wrap-around that gives me more eye protection, I'm dissappointed with how quickly the lense changes from light to dark. It is a rose color - as pictured - when you take them out of the case. But as soon as there is any light they darken (dark grey color). I've only used them once on a dawn patrol climb where they stayed light for any period of time. They seem to darken as soon as there is any sunlight present - including on cloudy days. My Julbo lenses are superior for this. But the Koos lense itself has good optics and no distortion. And for full on sun, they are nice. But my go-to remains Julbo reactiv lenses and the Koos will see limited usage.

Great cycling sunglasses. Takes away the sun glare. Stays on your face perfectly.
