Unanswered Question

On my last trip I lost one of the removable shields, do you sell it as spare parts?


Awesome, no regrets.

Use mainly for mountaineering, but also snowshoeing and hiking. Previous pair of Julbo Colorado glacier glasses had PC lenses that eventually got scratched up. These glass lenses don't have a flaw yet after 2 years of use and I never feel like I am squinting even on brightest of bright glacier days.

A few words about fit... These frames were a bit tight above the ears at first and didn't fit close enough to my face (they wanted to slip down my nose too easily. I didn't feel like temple adjustment alone was going to get the fit I wanted so I used hot water to bend/open up the bridge a bit for a better fit. Perhaps the XL's would have been a better fit without this mod, but I liked the look of the slightly smaller regular sized frames better.

I used the Julbo Explorer on my John Muir Trail thru-hike this fall and my eyes were so happy. I love how the side shades are removable for the not as sunny days. Also, these glasses are perfectly snug given the grip-tech feature. It's so hard to find comfy sunglasses for extended backcountry trips, but the Explorer pulled through. Give these a shot and you'll be happy you did.

I just got these glasses, I haven't tried...

I just got these glasses, I haven't tried them out as I haven't gone skiing yet.
I bought them for alpine skiing, I wanted to stay away from polarized lenses as in my experience polarized lenses do not allow you to see the terrain correctly.
The alti Arc lens is not polarized and I would be interested in any opinions or actual experience in using these lenses for skiing?

Glass (which is what the Alti Arc 4 material is) seems like an inferior option to the polycarbonate in other offerings. Polycarb would be much more shatter resistant in case of a mild wipe-out I would think.

Glass is in no way the inferior option. Not only do the lenses have less distortion and better overall clarity, but also they are FAR more scratch resistant.

The tradeoffs are weight (mineral crystal/glass weighs more) and the fact that they're not shatterproof (don't use these as safety glasses and be careful not to drop them).

Agree with alup on this. Glass is generally a superior material. Perhaps one other downside to glass is that they might fog up a bit easier in the cold, though I haven't noticed this in reality.
