I have managed to save some of the weight by using a rolling duffel. Eagle Creek 30" duffel is 9 pounds 6 ounces. The 25" is 7 pounds 12 ounces. Sure you don't have all the pockets and dividers inside but I hardly used them anyway. I would rather use the pack it cubes or 1 to 2 gallon plastic bags. The pack it cubes tend to add a fair amount of bulk so I don't use them regularly.
