IF U stay our of the rain there as good as any others....

 

I have a cheap pair with the foam and whatnot. I basically drenched the lenses in some of that "anti-fog" liquid and they were pretty good when I got caught out in the rain a few days later. Unfortunately the stuff didn't last too long and they went back to fogging shortly thereafter.

Also tried gobs of spit on numerous occasions (usually with trace amounts of tobacco juice which puts brown smears in my lenses)...doesn't work worth a sh#t.
