2.7 - Uniforms

2.7.1 - Each member of a respective team participating in a game must wear a uniform that clearly identifies that skater as a member of their team.

2.7.1.1 - All uniforms shall be in good repair and shall not cause a hazard to other skaters. All patches and numbers must be securely fastened to said uniform. Safety pins or tape are not permitted to attach or modify numbers to a uniform. Tape is allowed on helmets, pads, and jewelry; safety pins are never allowed.

2.7.2 - The team Captain must visibly display a “C” on their uniform or arm. The team Captain’s Designated Alternate must visibly display an “A” on their clothing, uniform, or arm.

2.7.2.1 - If the Captain is not able to skate the remainder of the game due to expulsion, fouling out, injury, or emergency, the team has the option to name a new Captain.

2.7.2.1.1 - In the instances where the rules call for a Captain to serve a penalty, and a team has not designated a Captain, the team may designate a new Captain at that time. Only if the team refuses to designate a Captain, the Head Referee will select the skater to be designated Captain for the remainder of the game and serve any applicable penalties.

2.7.2.2 - A team may not select a new Designated Alternate (skating or non-skating) should the Designated Alternate be unable to skate, coach, or manage the remainder of the game.

2.7.3 - Skater names on uniforms are optional.

2.7.4 - Each skater participating in a game must visibly display a unique (with relation to their own team) number on the back of their uniform.

2.7.4.1 - The print of the number must be at least 4 inches (10 cm) tall so that it is legible and large enough to be read by Officials who are positioned anywhere within the track or on its boundary.

2.7.4.2 - A skater’s number must be of a readable font. A number is of readable font if it can be easily read and distinguished from the other skaters’ numbers by the Officials, other skaters, and fans.

2.7.4.3 - A skater’s number may contain up to four characters.

2.7.4.4 - A skater’s number may include only Arabic numerals and Latin letters (uppercase or lowercase, but see Section 2.7.4.2), without accents: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z 1 2 3 4 5 6 7 8 9 0

2.7.4.5 - A skater’s number must have at least one numerical digit. For example, L5 is an acceptable number, but LV is not.

2.7.4.6 - A skater may have small characters preceding or following their skater number on their uniform (e.g., 55mph, where “mph” is considerably smaller than 55). These small characters are not considered part of the skater’s number and they may not inhibit the legibility of the skater’s number whatsoever. The maximum size for the small characters is 2 inches (5 cm).

2.7.4.7 - Skaters on the same team may not have identical numbers. For example, two skaters may not both wear L5, but one may wear L5 and another may wear J5. (See also Section 2.7.4.2.)

2.7.4.8 - A team’s uniform numbers must meet the definition of high contrast beyond a reasonable doubt or the Head Referee shall request that the team provide an alternative that meets the definition.

2.7.4.9 - A team’s uniform numbers are of high contrast if there is a large degree of visual difference between the color of the number and the base color of the uniform such that the number significantly stands out from the base color of the uniform.

2.7.5 - Each skater participating in a game must visibly display their number on each sleeve or arm. Numbers must be of high contrast and easily legible. Handwritten numbers on the arm are acceptable.

2.7.5.1 - Numbers may be placed on the hip or thigh in addition to the arm/sleeve. Numbers on hips or thighs must match roster numbers.

2.7.5.2 - Numbers may be placed on the helmet in addition to the arm/sleeve. Numbers on helmets must match roster numbers.

2.7.5.3 - The minimum height for a skater’s number on the arm/sleeve is 2 inches (5 cm).

2.7.5.4 - The maximum height for a skater’s number on the arm/sleeve is 4 inches (10 cm).
