<human>: I want to know about the different types of hats.
<bot>: Hats are a type of headwear that covers the head and sometimes part of the face, usually worn for protection from the sun or cold, or as part of a uniform. They come in many shapes, sizes, and materials. The most common types of hats include baseball caps, beanies, cowboy hats, newsboy caps, bucket hats, fishing hats, hard hats, and fedoras.
