The satisfying part of packing cubes is not necessarily squeezing in another outfit. It is opening your bag and seeing two manageable bundles instead of a collapsed clothing pile. Thule’s white compression cube set adds a second zipper for reducing bulk when the contents allow it.
Give each cube a job
The set contains one small and one medium cube. Separate everyday clothing from underwear or the items needed at your first stop. The translucent panels help you identify the bundle; grab handles make it easier to lift out without rearranging everything around it.
The expanded dimensions are about 26 × 18 × 11 cm for the small cube and 36 × 25 × 15 cm for the medium. Compare those footprints with the inside of your bag, not only its advertised litre capacity. A narrow backpack and a broad suitcase accommodate the same cube differently.
Compression has a limit
Load the main compartment without forcing it, then close the compression zipper gradually. Soft clothing can give; shoes and rigid objects cannot. A manufacturer’s empty compressed dimension is not a promise that your packed cube will become that thin.
Compression also leaves the contents’ weight unchanged. It can tempt you to exceed a baggage weight allowance by fitting more into the same bag. And it does not make shirts crease-free or turn water-repellent nylon into a sealed wet-clothing pouch.
Is the extra zipper worth buying?
Choose this set when your soft clothing routinely makes your bag bulge and you also want quick access to separate bundles. If ordinary cubes already keep your modest load organised, the upgrade may be unnecessary. For damp swimwear, use appropriate leak-resistant containment instead. The best outcome is a calmer packing routine, not a competition to make the suitcase impossibly full.
