Even though competition belts are worn less frequently than ordinary rank belts, they shouldnât be lower quality or less important. You donât wear them every day, true, but you wear them when you represent your art in competition, in front of an audience. Your art and your hard work to get to that level deserves high quality. Punokâs competition belts are 2â thick with eight rows of stitching. They meet World Karate Federation (WKF) standards, so you can proudly wear them when you compete anywhere on the globe. The light blue color of the blue belt distinguishes it from a rank belt of the same color.
