Covering for the head can refer to two items: a HOOD and a HAT. A HOOD is a type of clothing that covers the head and often the neck and shoulders. It is typically made of a lightweight material such as cotton or polyester. A HAT is a head covering that is usually made of a stiffer material such as felt or straw. Hats come in a variety of styles, including baseball caps, fedoras, and beanies. Both hoods and hats are used to protect the head from the elements and to keep it warm.
