A hard hat is a type of helmet predominantly used in hazardous environments such as industrial or construction sites to protect the head from injury due to falling objects, impact with other objects, and electric shock, as well as from rain. 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.
A kippah, yarmulke, or koppel is a brimless Jewish skullcap, usually made of cloth, traditionally worn by Jewish males to fulfill the customary requirement that the head be covered. It is the most common type of head-covering worn by men in Orthodox Jewish communities during prayers and by most Orthodox Jewish men at most other times. Among non-Orthodox Jewish individuals, some wear them at most times, while most wear them only during prayer, while attending a synagogue, or at other ceremonies, and others wear them rarely or never.
A hat is a head covering which is worn for various reasons, including protection against weather conditions, ceremonial reasons such as university graduation, religious reasons, safety, or as a fashion accessory. Hats which incorporate mechanical features, such as visors, spikes, flaps, braces or beer holders shade into the broader category of headgear.
In New Zealand, the United States, the United Kingdom, and elsewhere, a beanie is a head-hugging brimless cap, sometimes made from triangular panels of material joined by a button at the crown and seamed together around the sides. Beanies may be made of cloth, felt, wool, leather, or silk. In many US regions and parts of Canada the term "beanie" refers to a knitted cap, alternately called a "stocking cap" or a "toque".
The zucchetto or solideo, officially a pileolus, is a small, hemispherical, form-fitting ecclesiastical skullcap worn by clerics of various Catholic Churches, the Syriac Orthodox Church, and by senior clergy in Anglicanism.
A white hat is an ethical security hacker. Ethical hacking is a term meant to imply a broader category than just penetration testing. Under the owner's consent, white-hat hackers aim to identify any vulnerabilities or security issues the current system has. The white hat is contrasted with the black hat, a malicious hacker; this definitional dichotomy comes from Western films, where heroic and antagonistic cowboys might traditionally wear a white and a black hat, respectively. There is a third kind of hacker known as a grey hat who hacks with good intentions but at times without permission.
A grey hat is a computer hacker or computer security expert who may sometimes violate laws or typical ethical standards, but usually does not have the malicious intent typical of a black hat hacker.
A black hat is a computer hacker who violates laws or ethical standards for nefarious purposes, such as cybercrime, cyberwarfare, or malice. These acts can range from piracy to identity theft. A Black hat is often referred to as a "cracker".
Morning dress, also known as formal day dress, is the formal Western dress code for day attire, consisting chiefly of a morning coat, waistcoat, and formal trousers for men, and an appropriate gown for women. Men may also wear a popular variant, where all parts are the same colour and material, often grey, and usually called "morning suit" or "morning grey" to distinguish it; considered properly appropriate only to festive functions, such as summer weddings and horse races, which consequently makes it slightly less formal. The correct hat would be a formal top hat, or if on less spacious audience settings, optionally a collapsible equivalent opera hat.
Papal regalia and insignia are the official items of attire and decoration proper to the Pope in his capacity as the visible head of the Catholic Church and sovereign of the Vatican City State.
Clerical clothing is non-liturgical clothing worn exclusively by clergy. It is distinct from vestments in that it is not reserved specifically for use in the liturgy. Practices vary: clerical clothing is sometimes worn under vestments, and sometimes as the everyday clothing or street wear of a priest, minister, or other clergy member. Eastern Orthodox clerical clothing is a subset of a monk's habit.
A peaked cap, peaked hat, service cap, barracks cover, or combination cap is a form of headgear worn by the armed forces of many nations, as well as many uniformed civilian organisations such as law enforcement agencies and fire departments. It derives its name from its short visor, or peak, which was historically made of polished leather but increasingly is made of a cheaper synthetic substitute.
A kalimavkion, kalymmavchi (καλυμμαύχι), or, by metathesis of the word's internal syllables, kamilavka, is a clerical headdress worn by Orthodox Christian and Eastern Catholic monks or awarded to clergy. An approximate equivalent in the Latin Church is the biretta.
A security hacker or security researcher is someone who explores methods for breaching defenses and exploiting weaknesses in a computer system or network. Hackers may be motivated by a multitude of reasons, such as profit, protest, information gathering, challenge, recreation, or evaluation of a system weaknesses to assist in formulating defenses against potential hackers.
In various European countries, student caps of different types are, or have been, worn either as a marker of a common identity, as is the case in the Nordic countries, or to identify the wearer as a member of a smaller body within the larger group of students, as is the case with the caps worn by members of German Studentenverbindungen, or student groups in Belgium.
A religious habit is a distinctive set of clothing worn by members of a religious order. Traditionally, some plain garb recognizable as a religious habit has also been worn by those leading the religious eremitic and anchoritic life, although in their case without conformity to a particular uniform style.
This page details the uniforms and insignia of the Israel Defense Forces, excluding rank insignia. For ranks, see Israel Defense Forces ranks and insignia.
The uniforms of the United States Army distinguish soldiers from other service members. U.S. Army uniform designs have historically been influenced by British and French military traditions, as well as contemporary U.S. civilian fashion trends. The two primary uniforms of the modern U.S. Army are the Army Combat Uniform, used in operational environments, and the Army Green Service Uniform, worn during everyday professional wear and during formal and ceremonial occasions that do not warrant the wear of the more formal blue service uniform.
Religious clothing is clothing which is worn in accordance with religious practice, tradition or significance to a faith group. It includes clerical clothing such as cassocks, and religious habit, robes, and other vestments. Accessories include hats, wedding rings, crucifixes, etc.
In American films of the Western genre between the 1920s and the 1940s, white hats were often worn by heroes and black hats by villains to symbolize the contrast in good versus evil. The 1903 short film The Great Train Robbery was the first to apply this convention. Two exceptions to the convention were portrayals by William Boyd, who wore dark clothing as Hopalong Cassidy, and Robert Taylor's portrayal in the film The Law and Jake Wade (1958).
