This is the CAZA long sleeve, blue-belt rank BJJ rashie which is approved for IBJJF tournaments and competitions.
These rashies feature the CAZA name prominently on the front and the full CAZA logo on the back. The logo on the back includes the words ‘Noosa Heads’, the location of CAZA BJJ headquarters.
While students at CAZA gyms are free to wear any colour rashie during no-gi classes, tradition requires that you wear the colour of your current belt rank. If you are buying a rashie for someone else, perhaps choose a colour that matches their current belt colour.
