The Tatami Fightwear Deluxe Jiu Jitsu Competitor Black Belts are made from simply the finest materials, and finished to a impeccably high standard. The belts have a double folded pearl weave core, wrapped with a washed and super soft 100% cotton material. The belts are harder and thinner that our regular belts to allow for a might tighter knot, allowing your belt to stay on for longer. Each belt is finished with a white bar and an embroidered black on black patch for a sleek and simple styling detail.
