As a extensive business traveler, I have tried many packing organizers. The KIVA's are the best. Perfect size selection for different items, great colors for differentiation, and the zipper is the easiest, most convenient way to save space. Pack and zip -- it is amazing how much more you can fit in a suitcase. Can wrinkle clothes if you overstuff. Yet you can pack so much more!!! Makes it easy to get everything in a carry on!
I have used this product for 2 years, both the large and the small compression cubes, and I would not travel without them. I highly recommend these compression cubes to anyone who travels. They are far superior to the plastic compression bags that sooneer or later will leak and reinflate.
