I have the Willie Max slants with Easy Brackets. They are large enough for a leather jacket & more. If you go this route you will have to stiffen the back plates. I used plexiglass. I like riding around town without the bags. When I am ready for a road trip I just slide the bags on.

Young enough to care-less & old enough to know-better. Sooo how do you like me now!!! Whaaaat!!
