Beanie

A beanie is a soft, close-fitting hat which is usually made of wool, synthetic material, or fleece. They are worn low on the head, covering the forehead, and can be pulled down over the ears as well. There are two main varieties of beanies, those that hug the top of the head, and those that leave the top couple of inches of the hat unstretched on top of the head. These hats protect the head and ears from cold and wind chill, or are worn as a fashion item. They are also called woollen or wooly hats, or bobble hats if they are topped with a pompom.
