Hats can be divided into two categories, namely headgear and caps. Headgear includes such items as helmets, masks, hoods, and other protective gear worn by athletes or people engaged in hazardous activities. Caps are designed to protect the wearer's head from the sun or cold, and may come in a variety of shapes and sizes. There are also many specialized types of hat for specific uses, such as fishing hats, ski hats, and construction hats.
