What is hat over ears?

A hat over ears, also known as an earflap hat or trapper hat, is a type of headwear that provides warmth and coverage for the ears. The hat typically has two flaps that extend down from the sides to cover the ears, and can be tied under the chin to keep the hat in place. Earflap hats are often made from warm materials such as wool or fleece and are popular in colder climates. They are also used by individuals who engage in winter sports such as skiing or snowboarding. Earflap hats come in a variety of styles including traditional fur-lined trapper hats, knitted earflap hats, and more modern designs with faux fur or synthetic materials.
