Rules of Ultimate — Appendix v4.0

Appendix C: Uniform Requirements

C1.1. The primary purpose of these uniform requirements is to distinguish between players on opposing teams, and to identify individual players. This allows players, officials and spectators to follow and interpret the game correctly.
C1.2. They also aim to protect player safety and comfort, and fairness in the competition.
C1.3. Additionally, better quality uniforms are expected to convey a better image of our sport to the world, taking advantage of the media and spectator opportunities of WFDF events.
