We cannot travel without these now. We started a few years ago with one pack to keep things separated in our suitcase and fought over who got them and for what...so we each have 3 different sets and sizes for suitcases and carry ons.  When you go to unpack or find something..no digging, wondering where it is, sliding around luggage, etc. Everything is so organized and accessible. We have used them for short trips and long ones (overseas). Will always pack with ebags.
