These "packing shelves" make it so easy to pack and unpack.  When packing from home, I can hang it up and see exactly what I have packed so I don't have to fumble through my suitcase to be sure I have everything.  Then when I have it all ready, it collapses right inside my carry on.  While at my destination, can easily take it out and hang it up.  I really like the convenient laundry hamper!  Then when it's time to pack up, just drop it right back into the carry on.
