During official summer events (with temperatures starting from 25°C), all black belts and instructors are required to wear the official summer uniform, consisting of:
- Classic black trousers, tailored to ensure comfort and a polished, professional appearance
- Classic black shoes, clean and suitable for formal occasions
- Black belt with a silver buckle, symbolizing elegance
- Official black polo, embroidered with the World Ju-Jitsu Corporation logo for a uniform and distinctive look
This summer uniform is mandatory for all black belts, regardless of rank, when attending official events such as seminars, congresses, conferences, masterclasses, meetings, and workshops.
Designed to combine comfort and elegance, the summer uniform allows practitioners to maintain a professional image even in warm climates, while fostering a sense of unity and pride within the WJJC community.
Wearing the official summer uniform is not just a dress code: it represents dedication, respect for the martial art, and belonging to a great international family of martial artists committed to excellence.
By adhering to these uniform standards, members help preserve the prestige and identity of the World Ju-Jitsu Corporation at every event worldwide.
