Outdoor: Cat Crap Anti-Fog Lens Cleaner

I don't have much to say about EK Eksessories' Cat Crap Anti-Fog Lens Cleaner other than it works and it works well.

I was having frequent problems with my clear Tifosi glasses fogging up during night bike rides.  The good folks at REI suggested that I try Cat Crap to both clean the lenses and to prevent future problems with fogging.  I bought the product and applied it to my glasses.  Fogging problems: solved.
