Does anyone use one regularly? There is a school here that uses black doboks for black belts, as far as I know this is contrary to Kukkiwon guidelines. I believe they are only for black belts and I've also seen them use a crisscross diamond pattern dobok top. Is there meaning behind this? Also, who makes them? I know Mudo does, but I can't find many others. Does Adidas or Kwon offer a black V neck dobok?
