Gi ID Help needed

Hi all, I really could use someone's help. I"m trying to identify the GI that was used by the League of Shadow ninja's in the movie Batman Begins. I know a guy that actually had the real armor and gi. From what he remembers, he believe that it was a black, textured jujutsu gi, and believed was made by hyashi. He also said it might be a heavyweight ju jutsu very distinct thick weave material almost like the Ronin one and defo a throwing gi, with thick collar, so judo or Ju jutsu. Thanks in advance to anyone that reads this or can help out!
