A helmet is a form of protective gear worn to protect the head. More specifically, a helmet complements the skull in protecting the human brain. Ceremonial or symbolic helmets without protective function are sometimes worn. Soldiers wear helmets, often made from lightweight plastic materials.
A hard hat is a type of helmet predominantly used in workplace environments such as industrial or construction sites to protect the head from injury due to falling objects, impact with other objects, debris, rain, and electric shock. Suspension bands inside the helmet spread the helmet's weight and the force of any impact over the top of the head. A suspension also provides space of approximately 30 mm between the helmet's shell and the wearer's head, so that if an object strikes the shell, the impact is less likely to be transmitted directly to the skull. Some helmet shells have a mid-line reinforcement ridge to improve impact resistance. The rock climbing helmet fulfills a very similar role in a different context and has a very similar design.
The Phrygian cap or liberty cap is a soft conical cap with the apex bent over, associated in antiquity with several peoples in Eastern Europe and Anatolia, including Phrygia, Dacia, and the Balkans. In early modern Europe it came to signify freedom and the pursuit of liberty through a confusion with the pileus, the felt cap of manumitted (emancipated) slaves of ancient Rome. In artistic representations it signifies freedom and the pursuit of liberty.
A batting helmet is worn by batters in the game of baseball or softball. It is meant to protect the batter's head from errant pitches thrown by the pitcher. A batter who is "hit by pitch," due to an inadvertent wild pitch or a pitcher's purposeful attempt to hit him, may be seriously, even fatally, injured.
Stahlhelm is German for "steel helmet". The Imperial German Army began to replace the traditional boiled leather Pickelhaube with the Stahlhelm during World War I in 1916. The term Stahlhelm refers both to a generic steel helmet, and more specifically to the distinctive German design.
The M15 Adrian helmet was a combat helmet issued to the French Army during World War I. It was the first standard helmet of the French Army and was designed when millions of French troops were engaged in trench warfare, and head wounds from the falling shrapnel generated by the new technique of indirect fire became a frequent cause of battlefield casualties. Introduced in 1915, it was the first modern steel helmet and it served as the basic helmet of many armies well into the 1930s. Initially issued to infantry soldiers, in modified form they were also issued to cavalry and tank crews. A subsequent version, the M26, was used during World War II.
Czapka is a Polish and Belarusian generic word for a cap. However, it is perhaps best known to English speakers as a word for the 19th-century Polish cavalry headgear, consisting of a high, four-pointed cap with regimental insignia on the front to which feathers or rosettes were sometimes added.
A shako is a tall, cylindrical military cap, usually with a visor, and sometimes tapered at the top. It is usually adorned with some kind of ornamental plate or badge on the front, metallic or otherwise, and often has a feather, plume, or pompom attached at the top.

In classical mythology, the Cap of Invisibility is a helmet or cap that can turn the host invisible. It is also known as the Cap of Hades, Helm of Hades, or Helm of Darkness. Wearers of the cap in Greek myths include Athena, the goddess of wisdom, the messenger god Hermes, and the hero Perseus. The Cap of Invisibility enables the user to become invisible to other supernatural entities, functioning much like the cloud of mist that the gods surround themselves in to become undetectable.
The pileus was a brimless, felt cap worn in Illyria and surrounding regions, later also introduced in Ancient Rome. The Greek πιλίδιον (pilidion) and Latin pilleolus were smaller versions, similar to a skullcap.

The Lamellenhelm was a type of helmet used in Europe during the Early Middle Ages. Examples are characterized by caps made from overlapping lamellar scales, in addition to a brow plate, cheek guards, and camail. They are distinct from the contemporary spangenhelm and crested helmets also found in Europe; unlike those, which are influenced by Roman designs, Lamellenhelme display eastern influence and have primarily been found in southeastern Europe. They are mostly associated with the Avars of Pannonia and the Lombards of Italy.
