This is the CAZA short sleeve, black (kid’s) BJJ rashie. There is no black-belt rank for children in BJJ, so this rashie is for training only.
Our rashies feature the ‘CZ’ version of the CAZA logo prominently on the front. The back has a small, full version of the CAZA logo centred near the neck.
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.
