3.7 - Uniforms

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

3.7.1.1 - 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 fasten numbers to a uniform.

3.7.2 - 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.

3.7.3 - Skater names on uniforms are optional.

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

3.7.4.1 - The print of the number should 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.

3.7.4.2 - 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.

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

3.7.4.4 - A skater’s number must be alphanumeric with at least one numerical digit. For example: L5 is an acceptable number, but LV is not. Numbers cannot contain symbols.

3.7.4.5 - A skater may have small characters preceding or following their skater number on their jersey e.g. 55 mph, 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).

3.7.4.6 - 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.

3.7.4.7 - A team’s jersey 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.

3.7.4.8 - A team’s jersey 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 jersey such that the number significantly stands out from the base color of the jersey.

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

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