Packing Cubes vs Compression Bags

Packing cubes organize, compression bags shrink. Many one-bag travellers use both: cubes for daily clothes and a compression bag for bulky layers.

 Packing cubesCompression bags
Space savedModest, more with compression cubesLarge, especially for bulky items
OrganizationExcellent, one cube per categoryLimited, contents squashed together
WrinklesRolling in cubes keeps them lowMore creasing
WeightUnchanged, and a denser bag can get heavyUnchanged, easier to overpack
DurabilityFabric lasts for yearsPlastic valves and seals can fail
AccessQuick to open and repackSlower to re-compress

Choose Packing cubes if

  • You want an organized bag that is easy to live out of
  • You pack mostly t-shirts and light clothes
  • You change hotels often

Choose Compression bags if

  • You carry bulky jackets or sweaters
  • Space, not organization, is the problem
  • You pack once and rarely reopen

The bottom line

Start with packing cubes for organization, and add one compression bag if a bulky layer will not fit. Remember that compression saves volume, not weight.
