Some of the schools in my area use a pum belt with the red on top for first geub, flipping it over so that the black is on top for dan-bo. I don't really have an opinion on it; if it works within a school, then as far as I'm concerned, its fine.There has been a lot of discussion about the appropriateness of children wearing black belts. But what about adults who wear poom belts? How common is that, how advisable is that? For those who think adults wearing poom belts is ok, do you or your instructor also allow children to wear black belts?
