Have used some āanti-fogā wax before that I bought years ago at the MCN show at Ally Pally. It works well, but needs applying everyday on your glasses to work and was in the form of a solid stick, so was annoying trying to soften it upā¦the reviews of this sounded the same, but easier to applyā¦
Respro foggy - http://www.respro.com/popup_foggy2.php works perfectly for me when wearing glasses, fit to helmet & thatās it for the winter no more misted up glasses & no messing about with applying stuff or anything else.
