Best of both worlds.
- Zebra lenses have high-speed photochromic activation and darken almost instantly in bright light
- Anti-fog treatment is laser finished so it never rubs off
- Removable wings block light and glare from the side or can be left behind when you're back in the valley
- Grip tech sculpted inserts on the stems help these sunglasses stay put

Not as dark as expected
- Familiarity: I've put it through the wringer
It doesn't say it here on the backcountry.com page, but Julbo advertises these Zebra lenses as having a darkness range from category 2-4.
I already owned the Julbo Colorado glasses with the Spectron category 4 lens and I liked the idea of a pair of glasses that could get that dark but didn't have to be that dark all the time. I bought these and found that even in direct sunlight they do not get anywhere near as dark as my other category 4 lenses.
I emailed Julbo and was told that these only darken to the "lighter side of category 4". I don't know how they figure out the categories, but saying these darken to category 4 feels misleading. They are not dark enough for glacier travel or even rock climbing on a sunny day without squinting constantly.
Aside from the lens issue, they are comfortable glasses. Good for cloudy winter days skiing or climbing. I have a pretty big head and the glasses do not stay on very securely in an activity like running. If I'm sweating hard, I find myself pushing them back up my nose every 30 seconds.
I ordered another pair with the normal Spectron 4 lenses for glacier travel.
