Human: I'm trying to find out about the history of the cowboy hat. Assistant: 
The cowboy hat is a traditional headwear for cowboys, and has been around since the late 19th century. It was originally made from felt and leather, and had a brim to protect the wearer's face from the sun. Over time, it evolved into its current form with a wide brimmed crown and a flat top. Today, cowboy hats are typically made from felt, straw, or synthetic materials. They can also come in a variety of colors, patterns, and designs.
