If you’re a frequent traveler and want something that’ll hold up to many trips a year, go for the Shacke packing cubes. They’re made out of water-resistant nylon, come with double-stitched lids that will stay in place. They’re four inches deep and hold multiple pairs of jeans, shirts, and underwear. A set comes with four sizes, and the included storage bag works double duty as a travel laundry bag. They come in colors like black, green, and orchid.
