This is the perfect size
"This is the perfect size for all of my toiletries as well as two (Briggs & Riley) packing cubes, bedroom slippers in the front pocket, electric tool brush and electric razor with some room to spare. I plan to take it and a roller bag to Europe next Spring for two weeks and using it has freed up some space in my roller bag. The back sleeve also works well with my roller bag especially the fact that is is not too wide and as a result doesn't hang over the ends of the roller."
