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

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 tycoon to beach-goer to backpacker.

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.”

While we’re all deep into planning our spring break and summer trips, we’ve rounded up our favorite and expert-approved packing cubes across the internet, including picks from Away, eBags, J.Crew and Amazon, many of which get Wiss’ stamp of approval.
