Since you might not be able to fit everything you need for a week-long excursion into a rolling duffle bag, however, it can work as an addition to your current checked luggage or carry-on bag.

A total of 129 items fit in the four bags – two underseat and two carry-on size – when rolling, compared to 121 rolling, 118 using compression cubes, and 113 using vacuum packing.
