You can also use woman's panties, preferably used for a few days so there is some dampness. If they are from a small woman you can just use the leg holes to attach them to your ears. If you have a large woman like me then you can wear a motorcycle helmet with the visor raised, pull the big girl panties down over the helmet, the elastic will grip your neck.

I get strange looks when I ride down the road but they won't be laughing when they can't breathe soon. I will be fine.
