The red Patch or Brag Vest is used as one place for scouts to display temporary patches. It is not an official part of the uniform, even though it is sold in the scout store.
Since it is personal clothing, can a pack, den, individual, etc. design a different temporary patch display method? What about a red felt sash similar to the Boy Scout merit badge sash? Or what about a red windbreaker?
Not being official uniform, it like the patch vest, could not be worn for uniform inspections and should be discouraged at formal ceremonies.
