My wife and I have been traveling internationally since about 1985 to about everywhere except Antarctica and Siberia. We decided to replace the "internal" bags that we use to sort out clothing in our suit cases of duffel bags, as the case may. We are delighted with the offerings from Eagle Creek. The fabric is very strong and amazingly light. There is no space wasted on the bags of superfluous padding. The design allow one to pack loosely or to compress the garments for extra space. Too often inserts take up too much space, but not these. We bought two colors so we do not confuse our bags.
