Vacuum storage bags work. The vacuum cleaner you normally need to use them does not fit in a suitcase. This one has the pump built into the bag, so it compresses wherever you are — including a hotel room the night before a flight home with more than you left with.
A winter duvet or a season of coats comes down to a fraction of the shelf space. It also seals against damp and dust while stored, which matters more than it sounds for anything going into a loft or under a bed.
