I have a Giant Loop Tillamook dry bag that can go up to 48L. It had roll top type opening on both sides so you can expand or contract the size easily. Some scuffs but no damage to it whatsoever, will trap air inside if you roll it up so no holes whatsoever. My Rally's rack is just too small and the bags shape causes it to rest on the exhaust shield. Whilst it was no problem on my last trip I just dont like it as the plastic shield will eventually give way and potentially damage the bag. Hopefully someone has a Wolfman expedition small duffle to swap ? I already have Wolfman dry saddle bags. Will take some pics later, same as the one in the picture.
