While cleaning out my desk the other day, I came across some old supplies I used to use in middle school. It led me to a great idea that's not only cheap, but works quite well, here's how it goes:
1. Get any old book cover ($1 at Wally's) preferably a large or jumbo size (depending on how tight you want it)
2. Cut off one end (right at base) to create head hole to slip in
3. Slip onto head. Although this looks goofy at first, it still creates a great tight layer that covers every part of the head except for the eyes
4. Put on helmet and goggles and enjoy. It becomes a nice breathable layer that still keeps the wind out. Not only this.... but it's basically free. You just cant beat that.
