It's a clever solution for touring or if you always carry the same stuff, but in my case it's almost always different stuff, odd shapes and the like, etc. etc. So I need something like a soft inner bag with compression straps that can be attached to the floor so stuff won't bounce around.

Bungee net won't do as it's a PITA to get at the mount points at the bottom to tie it down.

Figured I'd ask before trying to sew something from scratch. Bumot makes soft inner cases for their panniers but not the top cases.

 

I was thinking some sort of divider too, maybe even zippered bags to keep stuff together. A search of Amazon, eBay or Ali may turn something up.

 

Turns out Bumot makes soft inner bags for their top cases. Just not currently available.

 

Kathy’s Journey bags are the bees knees if you want liners/bags custom made to fit your top case. Great small woman owned business with stuff made in Floyd Va. and all products have a lifetime warranty and available in 9 different colors.

I have had Kathy's bags for Vario paniers for years that I love and have served me extremely well. I recently scored a 3-bag set (panniers and top case) for OEM BMW GSA panniers and top case for 66% off retail.

 

I have a diaper caddy in my top box from Amazon…$10 I think. After having a water bottle rub a hole in a brand new dry bag I started looking for something. Built dividers and a false bottom in the side bags as mentioned by Mx14 and started to do the same for the top box…spotted the caddy while looking for something else

 

I wonder if a camera case might be helpful? They have foam dividers for lenses, etc with adjustable velcro attachments. A strap (or old belt) to cinch it tighter could be added.

 

+1 on the camera/lens case. This is the one I use in the topcase (it's the bomb): Amazon.com
Fits the Vario top cases like it was made for it when in low position. With Vario expanded, leaves room on top for clothing, etc.
Also in black: Amazon.com

 

Check aliexpress for 'camera bag inserts' they have various size and shape of organizer to convert any bag or case in a padded camera bag with adjustable compartiments.
