The Eagle Creek Pack-It System is wonderful for the frequent traveler. This system works to fit the most clothing in your suitcase in a neat and organized fashion and keep it wrinkle free. The system consists of folders for shirts, blouses, pants, slacks and dresses which are folded and stacked inside the folders which keeps them neat and wrinkle free. The Pack-it cubes come in various sizes andare used to contain socks, underwear, t-shirts, etc. These are then packed along side the pack-it folder to fill in along the sides of the suitcase. There are also various other tubes, and packs for shoes, etc. The system is available in lots of colors as well as black.
I used this system on a 14 day trip to Japan and was able to pack everything I needed for the trip. This system is great with the new regulations from the TSA as they can readily see everything, take the clothing out and put it back neatly without your clothing being disturbed. I was skeptical about the system originally, but now I won't travel without it Buy a piece or two and give it a try.
