Best for cubes that actually compress
Peak Design Packing Cubes
A real compression zip rather than a decorative one, and an internal divider for clean and dirty. The cube that justifies the volume it costs.
If you are going to use cubes, use ones that compress. A cube with a single zip is a fabric box that tidies your bag; a second compression zip actually reduces the volume of what is inside, which is the only way a cube pays back the space its own fabric occupies.

Specs
- Two-zip design: pack open, then compress
- Internal divider separating two sides
- Recycled nylon shell with a mesh panel
- Small and medium sizes
Good for
- The compression zip removes real air volume rather than just tidying the shape
- The internal divider genuinely solves the clean-versus-worn problem on a long trip
- Keeps a rectangular shape, which is what makes cubes pack efficiently
Bad at
- Expensive for fabric bags, which is a fair criticism of the whole category
- Compression makes wrinkles worse, which no cube can avoid
- The divider is fixed, so a one-sided load wastes half the cube
