In my adopted new hometown in a very Italian city in Northern New Jersey, I have discovered a new word for what I have always heretofore called a "knit cap" or a "winter hat." It's a word everyone here knows how to say, but no one I've asked knows how to spell. It sounds like "goobalini."

I had a friend who owns the Dictionary of American Regional English look it up, and she found nothing. So my three questions are: 1. How do you spell it? 2. What is its origin? 3. Where else do they say this?

Can anyone help?
