Progear Anti-Fog is a Fog-Free soft gel to spread an ultra-thin, invisible, dry coating onto a lens surface that absorbs moisture. Fog micro-droplets are absorbed into the coating, instantly spread across its surface, and evaporate back into the air before fog can form. Supplied with a microfibre cloth.
Zeiss also has an anti-fog available here:
