Just finished a converstion with John Ervin. He stated he will allow any style Shuai Chiao jacket. They must be a thick heavy weight material jacket. He will not allow modified karate Gi’s. I think the Combat Shuai Chiao guys modify their karate gi’s and thats why they are a bit cheaper.
So if it looks like something other than a SC or Judo jacket, then it will not be allowed.
