- The merit badge sash is available in 30 and 36 inch lengths
- Merit badges are worn on the front of the sash
- The Varsity Letter with earned pins and bars may be worn on the bottom front corner of the sash
- Additional merit badges and temporary insignia may be worn on the back of the sash
- The sash is worn over the right shoulder and is never worn folded through the belt
- The merit badge sash and the Order of the Arrow sash may not be worn at the same time
- Only one merit badge sash may be worn
