Quick answer

A compression packing cube lets you fit more into your carry-on by flattening bulky items. Follow these steps to maximize space without overstuffing.

Why compression cubes work better than regular cubes

Regular packing cubes organize but don't shrink volume. Compression cubes add a second zipper that squeezes out air, reducing the bulk of soft items like sweaters, jeans, and jackets. The trade-off is that rigid or structured items (shoes, electronics) don't compress well and may waste space if forced into a compression cube.

Step-by-step guide

  1. 1. Choose the right items: Pick soft, compressible clothing: t-shirts, sweaters, fleeces, jeans, and lightweight jackets. Avoid shoes, toiletries, or anything with rigid structure. Compressing rigid items can damage the cube or waste space.
  2. 2. Fill the cube evenly: Lay items flat inside the cube, stacking them evenly. Don't overfill—leave about an inch of space at the top so the compression zipper can move freely. Overstuffing makes the compression zipper hard to close and reduces effectiveness.
  3. 3. Zip the main compartment: Close the main zipper fully. Make sure no fabric is caught in the zipper track, as this can cause snags or prevent smooth compression. A clean zip ensures the cube seals properly.
  4. 4. Compress with the second zipper: Slowly zip the compression zipper around the cube. You'll see the cube shrink as air is forced out. Work in small sections if the zipper feels tight. If the zipper won't budge, you've overpacked—remove one item and try again.
  5. 5. Place in your luggage: Position the compressed cube flat in your carry-on. Stack other cubes or items on top. The flat shape maximizes usable space. A compressed cube is denser, so it stays put better during travel.
