I have been using the Aerospace goggles for the last year - mine have the zebra lenses - and have been very pleased with them in all conditions except flat light.
The lenses are very crisp and your vision is acute and clear. The photochromic lens changes quickly and is great for skiing a wide open slope, dropping into a shaded chute, ducking into the trees, and then popping back out into full sun. I never felt like I was struggling to deal with the brightness level. Even low-light when the sun was going down or coming up, I never felt like I wished I gone with the Zebra Light lenses.
My biggest complain is that I absolutely cannot use these in flat light. Granted I have an astigmatism, which I've been told makes flat-light conditions all the more difficult, but without a little help from the sun, I can't see the slightest bit of contour or texture on a slope with the Zebra lens. Now, I certainly am not complaining about this, I don't expect a single pair of goggles to do everything perfectly, this is just what I have found to be their achilles heal.
On to the frames - The large lenses and frames give you great field of vision (oh, the snazzy, Euro, tunnel-vision-goggles of old, how I do not miss you). The pop-forward lens to ventilate works extremely well - though after popping them forward the first time I haven't been able to secure them fully-shut again (though, honestly I haven't needed to).
Whether you're skinning up in blustery conditions, or going the lazy route on a lift, these goggles give you protection and excellent ventilation. Sure, they'll fog from time to time - particularly in a hard effort - but as you get your heart rate back down out of the red zone they clear up very quickly and I haven't had any issues with compromised vision when I needed to be able to see clearly - but, please note, I don't race, so I can't speak to their usefulness in that space. As I do more fitness skinning this winter (who knows maybe a race or two could be in my future in coming seasons), I'll see how the ventilation works when I'm really doing consistent high-output skinning and booting, but I'm guessing they'll be pretty solid.
As an update to my previous review, I have just added a pair of the Zebra Light Red lens goggles to my assortment, and am incredibly happy with the results - they are the perfect compliment to the standard Zebra lenses and have completely taken care of my issue with flat, diffused light. I skied these a week ago when it was gray and snowing, but with sunlight behind the haze that was making things very difficult driving to the mountain, but as soon as I got out, geared up and put on the ZL Red goggles, things were clear as could be. The definition and detail were everything I could have hoped for.
I was between the Julbo goggles and the Smith Chroma Pop with the light orange lenses. I'm very happy with my decision to stick with the Julbos. I'll keep the regular Zebras for bright days, because they are great for those. But the Zebra Light Red lens is perfect for everything that the regular Zebra isn't.
BTW - The Zebra Light Red lens is in the goggles listed as "Zebra Light, Black"
Great review! I am reaaaaally interested in the Zebra Light Red lenses. I also have Zebras and love them except for flat out days where I definitely don’t like them! I suffer astigmatism too (I didn’t know that it could affect my vision in flat light, which is actually quite bad!). Great to know that these lenses are better than the traditional Zebras!
Have you compared the ZL Red with other high-contrast lenses (Oakley Prizm, Giro Vivids, the Chromapops,...) by any chance? THANKS!
Also, have you noticed if the photochromatic technology slows down when the day is really cold? I have read some people complain about the lens going dark and then not changing at all from there... I have experienced it to some extent in my 7-yr old Zebras, but just wanted to check...
