I took the plunge and purchased these and used them at Mt Baker in late March.
It was snowing most of the time I was there and on day one it was as wet as I have ever been but these goggles didn't fog up and offer the best view I have
experienced in my ski career. I gave them to the others in my group to try
and they all agreed they were outstanding. I wasn't aware of the lens changing density but I could always see perfectly so I am sold on these things.
