No offense, people, but the people who suggest HeadSweats or something to soak up moisture under the helmet apparently don't sweat, they do good to last an hour without needing a fresh one (as has anything else I have tried). I go through about 3 changes of clothes working outside during the summer, forget about cycling or running. I am going to have to try the wax. Nothing worse than having the vision blurred by sweat on the lens.
