Another pro-vue user here!!! I have used both the fan turbo as well as the basic and I like the basic one better. The fan batteries died pretty quick as well as having the batteries on the side of my head.
I use them for ATV, skiing as well as snowmobiling and have been very pleased. I usually have to take them apart a couple times a year to clean them, but other than that no complaints. They also will fog up when I am really huffing and puffing when I am stuck or they get moisture in them, but I think any goggle would under those conditions.
All in all, I have been very pleased. I haven't checked for awhile, but pro-vue could update their goggles from something other than the 80's.
