What is a "sun hat"?

A sun hat is a type of headwear designed to protect the wearer's head, face, and neck from the sun's rays. Sun hats are typically made from lightweight and breathable materials such as straw, cotton, or polyester and often have a wide brim that provides ample shade. Some sun hats also feature a neck flap or a veil that can be draped over the face to provide additional protection from the sun. Sun hats come in a variety of styles, including bucket hats, floppy hats, and visors, and are commonly worn during outdoor activities such as hiking, gardening, and beach outings.
