I am a compulsive over-packer. I’m hoping to go to Italy next year and have been working hard on trying to significantly downsize my packing. It would be like winning the Olympics if I could ever get everything into a carry-on size suitcase!
I’ve used regular packing cubes for years and love them but just saw on a travel bog that they also have compression packing cubes (similar to regular packing cubes but then they also have an extra zipper that compresses what’s in the cube). I may try some of the Amazon ones. I assume they wrinkle your clothes more but I’m curious to see if they would actually free up more space.
