Vacuum Bags
I do not remember when I first encountered vacuum bags. It must be many years ago now and I can not imagine moving or travelling without them.
Vacuum bags are designed to reduce the storage size of your bedding or clothes. They are plastic bags that allow air trapped inside to be pumped out. You put your clothes or linen inside, then you vacuum out the air. The result is an impressively shrunken rigid bag.
