To minimize confusion for the referee, Rule 6.1 requires the goalie to wear a jersey that is a different color from either team's jersey. He is the only player on the squad that can use his skates to transfer the ball to a teammate. A goalkeeper is allowed to leave his position to receive a free kick or penalty kick if necessary.
The goalkeeper wears a uniform of white pants with a black belt and black shoes. The uniform may have colored trim but it must be in distinct squares or circles (such as red around the chest and back) to distinguish him from other players who may be wearing orange or yellow shirts under their jerseys.
He also wears a helmet designed to protect his head while he is defending against shots from the field. Goalkeepers are required by law to wear protective equipment when they are not wearing the uniform of their team. For example, a goalkeeper would not be allowed to play in the NHL without a helmet since the rules state that "Goalkeepers must wear helmets."
In addition to the requirements in the rule book, most professional soccer leagues also require goalkeepers to wear sunglasses during games. The reason for this rule is so that the goalkeeper does not lose vision of the ball while he is playing. If he removes his glasses, he could possibly be penalized or even ejected from the game.
Why is the goalie's jersey a different color? According to FIFA rules, the goalie on each side wears a different color than his colleagues in order to differentiate himself from his teammates and other field players. He is also the only player who is permitted to use his hands. This is why most goalkeepers wear a red helmet and stick; they want to be seen by players and fans alike.
In fact, goalkeepers have been wearing uniforms of different colors since the beginning of soccer. The first official international match was played on November 11, 1869 between England and the United States. Charles Alcock, who was then the goalkeeper for the English team, wore a white uniform with blue trim. American goalkeeper Amos Davenport wore a black uniform with yellow trim during that game. These are the original colors used by goalkeepers today.
In 1930, the International Federation of Association Football (now known as FIFA) introduced some changes to improve the quality of play. One of these changes was requiring all players, including goalkeepers, to wear colored clothing during matches. This rule was designed to make it easier for referees to control the flow of the game by letting them know which players were able-bodied enough to be on the field.
There had been attempts in previous years to introduce a rule requiring goalkeepers to wear specific colors, but they never became laws. With this new rule, goalkeepers quickly adopted the colorful uniforms we see today.
Soccer goalkeepers can wear the same color jersey as each other throughout a game if neither goalie possesses a different color replacement jersey. If the goaltender's outfit matches that of the other team's goalie, the referee may allow the game to continue as scheduled.
Some leagues and clubs have special uniforms for their goalkeepers; others do not. Whether a goalkeeper wears a uniform or not is up to each individual club. Some keepers may prefer not to wear a uniform because they feel it gives them an unfair advantage. Others may believe it makes them easier to identify on the field. Whatever the reason, each keeper must be allowed to make his/her own decision about whether to wear a uniform.
In general, black is the preferred color for goalkeeping jerseys because it does not reflect light and thus makes seeing the ball more difficult for opponents. However, white is used frequently in certain countries such as England where many keepers are dressed in white to indicate to the fans that there is no one available to stop a penalty kick. Other colors such as red, yellow, and blue can be used by keepers if they like but most teams tend to stick with black or white.
Keep in mind that while goalkeepers can choose what color they want to wear, trainers must be worn during games played outside of the United States.
Players wear jerseys with numbers, shorts, and socks that indicate the team they are playing for. Shoes and shin protectors are required. The jerseys of the two sides must be clearly identifiable, and the goalkeepers must be recognizable from all other players and match officials.
There is a list of what each player wears at any one time during the game. This varies depending on whether the player is active or not, but generally things like shirts, jackets, trousers, and helmets are removed to allow room for injury treatment. Players may also have stickers or patches attached to relevant parts of their clothing to show support for friends or family members who are sick, injured, or dying.
Jerseys are made of cloth and are roughly divided into two main categories: home and away. The home jersey is usually white in color, while the away version can be any color other than black or gray. Some teams have different colors for home and away games; these are called "colored" jerseys.
Some clubs have separate outfits for first-team and reserve players, which are worn during consecutive league matches. These are known as "change of shirt" periods.
Finally, some players wear special uniforms that identify them as being a referee or linesman. These are colored according to which part of the game they are officiating - red for referees, yellow for linesmen.
