I think this review will have to be updated after I get way more use out of my gear, but so far, I really appreciate these compression bags. They pack like packing cubes, which works pretty tidily if you roll your clothes, but you can also get a decent amount of compression out of them with the integrated zipper. I have been able to fit all my clothes into a larger one and compress it a significant amount, and use the medium size one for socks, underwear, etc. The inside of my backpack is now super segmented, and nothing gets disarrayed if all I want to do is change into my sandals. I have been using a ziplock inside the packing cube for dirty or damp items, which has been working so far.

Note: we also have a set of non-compression cubes in three sizes. We are using one for shoes, one for prescription medicines, and one for a miscellaneous bag. While these are acceptably functional, I would recommend buying the compression style instead. Even if you have all noncompressible items in the bag on one trip, if you don’t need the full space of the compartment, the compression feature allows you to use the same packing cube in a range of thicknesses.
