I fog glasses pretty easily, but am looking for max protection. Nobody is specifying which lens they are using on these reviews. Looking for opinion on glass vs camel vs spec4. Gonna be on 14ers in a few weeks, and hopefully Rainier next summer. Thanks!!

I have alti arc version and they seem to fog VERY easily. At least on my face. Still I do love them and would recommend to others

(I've never used the Camel anti-fog lenses. My lenses never fogged on me, though I have a narrower face which means the explorers didn't completely seal off all air. Hope this helps.)

I have the Explorer with the alti-arc glass lens. I didn't mean to get the glass specifically, but I used it on a 12-day mountaineering course in the Alaska Range--and loved them! Several others in our group had the Spectron lenses (the polycarbonate ones). From what I've heard, the glass lenses scratch less easily, though potentially are weakened if they do scratch and may be slightly heavier. Polycarbonate lenses are safer but scratch much easier, though they are not weakened when scratched. Again, please confirm this with Julbo as I have only heard the glass vs. polycarbonate via hearsay. Anyways, the alti-arc glass lens is not mirror coated while the Spectron lenses are. Again, I loved my glasses, and they performed amazingly well. It was extremely bright out on the Kahiltna Glacier--like walking in a solar oven, yet my eyes never fatigued whatsoever.
