I have ridden my bike to work everyday for the past two years. Last winter I bought a cheap knitted ski mask and while it's better than nothing, the cold wind seems to penetrate it rather easily.

I'd appreciate any feedback from the cold winter commuters here. I don't want to spend a fortune, around 30 dollars and below would be great. What makes a good mask?

It's 12 degrees fahrenheit this morning, I'm done freezing my face off!
