A topi is a type of hat that is typically worn in parts of Africa and South Asia. It is usually made of a lightweight material such as cotton or straw, and is designed to provide protection from the sun while still allowing for air circulation to keep the wearer cool. The topi is characterized by its flat crown and wide brim, which provides shade for the face and neck. It is often worn by hunters, travelers, and others who spend a lot of time outdoors in sunny conditions. In some cultures, the topi is also worn as a symbol of social status or as part of traditional attire for formal occasions.
