I forgot about the hanger on the back. It is too narrow. when you run a belt through it it will serve as a pivot point, with the sporran tending to swing to and fro when you walk. Just widen the hanger by a factor of about three and it will work better. Sporran straps are never more than about an inch, so if the hangar had an inside opening of 1.5 inches it would be more than adequate.

And I like the use of the magnetic clasp.
