need to keep the coooold wind out of my ears! and giro helmet ?

I use a Smartwool liner in winter and it keeps me toasty warm. The nice thing about it is that although it keeps my head and ears warm it is thin enough to fit under my helmet without my head feeling squished.

I like the Smartwool helmet liner as well. It covers right over your ears and doesn't ride up either. If it's quite cold, though, I'll put on my thin Louis Garneau junior balaclava which protects my ears and neck, cheekbones and chin too.
When it gets SUPER cold I'll add my SW liner to the balaclava!
