Eagle Creek Pack-It Cubes help you organize your travel clothes and reduce wrinkles.
Pack-It Cubes come in a variety of sizes to take advantage of available spaces. Use them in luggage, back packs, duffle bags, paper bags, or by themselves.
You can use different cubes for different days or type of clothes. You can color code how you organize your clothes (underwear in blue, blouses in red, etc.). If people share a suitcase, you can easily identify whose clothes are whose.
Some cubes are single sided, some are two sided. Some have a water resistant side to carry damp clothes.
Now that many airlines are charging by weight, I almost always pack in 'parachute bags' and organize the contents with Pack-It Cubes. The parachute bags are easy to carry on your shoulder, and are easy to adjust to fit into odd spaces in the trunk of a car.
Although Pack-It Cubes may seem a bit expensive (at $10 to $18 each), they last for years and give you a lot more flexibility for how you pack.
