I think any good motorcycle bag will work. I prefer ones that have a waterproof cover to put over it when needed. The problem is where to tie it down. Wing Stuff has these https://wingstuff.com/products/33309...eat-bolt-combo that I added and it helps, the pointed bolts are nice also. Additionally I added two on each side eyelets to accept with ease bungee hooks, two in the bike and two on the MP3 rack.
