I have only worn them for one weekend camping trip, but I had them on from 8am to 8pm. They are light enough that you don't feel like you are wearing anything. The photochromatic lenses range works so well that it feels like there is a constant sunlight strength all day. Very easy on the eyes. Would definitely recommend to anyone.
I'm a serious amateur triathlete and these shades are perfect. The size is just right, the field of vision is completely unobstructed, they weight almost nothing and they adjust to the amount of ambient light. I would recommend these to any athlete.
So light anx stable you forget about them. With the zebra light lens you can canwear them from before sunset to after sun down
Excellent glasses - I have a pair of Aero glasses with Zebra lenses. I’ve worn them while cross country skiing in both bright and cloudy conditions. Also while trail running and they transition well from direct sunlight to darker conditions in the trees, and into the evenings.
Excellent product. Surpasses my high expectations. Julbo FTW!
