If you’re not using packing cubes already, then let us introduce you to your new favorite on-the-go organizers and travel accessory.

Both novice and expert travelers swear by their usefulness. With them, you can keep your clothes, accessories and more organized and in their own zippered compartments. When it comes time to pack, arrange them in your suitcase Tetris-style to ensure everything fits. Once you try packing cubes, you won’t be able to travel without them again.

What are packing cubes?

Available in nylon, mesh and many other soft materials, packing cubes are essentially zippered pouches of differing sizes that allow you to organize the contents of your suitcase. They’ve become ubiquitous for all kinds of travelers — from business tycoons to beachgoers to backpackers.

“Packing cubes keep your luggage from becoming a mass of things to root through while you’re traveling,” says Amanda Wiss, founder of New York City-based home organizing firm Urban Clarity. “Whether you are a painstaking packer planning weeks in advance or you whip it all together at the last minute, after a day or two into the trip, keeping things organized and handy becomes a struggle. That’s where packing cubes come in.”

In addition to streamlining the process of packing, the little taskmasters help keep you organized during your stay. “Not only do they sectionalize your things and keep them protected and clean,” says Wiss, but they also “help provide a ‘home’ for every item, which is key for organizing any space.”

How to use packing cubes

The best part about packing cubes is that you can use them how you want. Prefer to keep your socks together? Dedicate a packing cube to them. More interested in keeping clothes of a certain color in one area? Pack a cube dedicated to your favorite green clothes, or put your packing cubes to use beyond clothes — a space for storing all of your cables or beauty favorites in one place.

Customize how you use your packing cubes in order to stay the most organized. When your trip is coming to a close, consider dedicating one (or more) of your cubes to your dirty clothes. That way, you can ensure that your dirties don’t touch your cleans.
