You can slap a shirt on a referee and they'll wear it. We took the extra step and spent three months working with referees from The Summer Series to craft what we would call almost the perfect refereeing shirt for New Zealand. The design was structured to allow a stable airflow to keep the official cool, hold a communication microphone inside of the shirt for reliable comms between the replay official and the official on court and provided a cut that wouldn't rip the shirt but allow a microphone and communication earpiece to be fitted without annoying the referee and affecting performance. Built by officials for officials.
