I had one of the original ones and the lenses always fogged up in the cold rain or cool moist air. They sent me news lenses and they did the same thing. After that I started using a helmet and love it. Last year I bought a new save phace to use on light rain days. It did the same thing about fogging up so I took it back. It real dangerous going 70 and not being able to see since the mask fogged up.
Same thing for me. They kept telling me they had the fogging issued solved. After about 3 times getting the "New Anti Fog Lens" I was done with them.
Sold my SavePhace and I am done with them. False Advertising in my opinion.......
