The "Buzz Kidder" sporrans are designed to go with the sporran strap, or on a belt. I have one and wear it both ways... depending on the use.



Notice that there are the clasps for the strap, and a "pass-through" for the belt.

Otherwise, he has a belt designed with the corresponding clasps for the sporran too.



Either way, it's a great alternative to wearing it on the front apron.
