The Best Packing Cubes: 4 Compared (and One to Skip)
We compared four packing cubes on published volume and dimensions, weight, compression, fabric and zip specification, visibility and warranty.
The short version
The Peak Design Packing Cube in Medium is the one to buy: 32 by 17 by 8 centimetres compressed and 32 by 17 by 17 expanded, 4.5 litres compressed and 9 litres expanded, 110 grams, with an internal divider that separates clean clothes from dirty and lets each side expand independently, an expansion and compression zip, a 100 percent recycled weatherproof 70D ripstop that self-heals small punctures, and a lifetime warranty. The Matador Packing Cube Set 3-Pack is the value pick and publishes almost as much: three cubes at 7.5, 5 and 2.5 litres weighing 68, 56 and 44 grams, with see-through mesh windows, high-visibility interiors, YKK two-way zippers and recycled materials meeting Bluesign criteria. The Eagle Creek Pack-It Reveal Compression Cube Set gives you two mesh-topped compression cubes in 100 percent recycled water-resistant fabric, backed by the No Matter What warranty, and publishes no dimensions at all. The Cotopaxi Cubo 6L is the one to skip, because its entire product description is that it is an expandable packing cube. Best for: anyone whose suitcase is full before it is packed.

The verdict in 30 seconds
What mattered most
- Volume
- Dimensions
- Weight
- Compression
- Visibility
- Fabric
Packing cubes do two separate jobs and most buyers only think about the first. They organise, so you can find a shirt without excavating a suitcase, and they compress, so the same clothes take less room. A cube that only organises is a fabric box; one that compresses turns a full case into a half-full one. The specification that matters most is therefore volume, ideally given twice, once uncompressed and once compressed, and the second most useful is weight, because a set of cubes adds mass to a bag that may already be at an airline limit.
Volume published twice, an internal clean and dirty divider, and a lifetime warranty.
Best for: Frequent travellers who want one cube specification they can trust and the clean-dirty divider.
- Both states are published: 32 by 17 by 8 centimetres and 4.5 litres compressed, 32 by 17 by 17 centimetres and 9 litres expanded, with an expansion and compression zip to move between them.
- An internal divider separates clean clothes from dirty, and each compartment expands and contracts independently as its contents change, which is the most genuinely useful feature in this comparison.
- 110 grams, built from 100 percent recycled weatherproof Versa Heal 70D ripstop that self-heals small punctures and abrasions, with number 5 UltraZips sewn with abrasion-resistant thread and a lifetime warranty.
- Sold as single cubes rather than a set, so filling a suitcase means several purchases at premium prices.
- The self-healing property covers small punctures and abrasions rather than tears.
- Peak Design gives an example capacity of 10 t-shirts when expanded, which is helpful but is the only capacity guidance offered.
- It is by a clear margin the most expensive cube here per litre.
Three sizes with a volume, a weight and a dimension published for each.
Best for: Getting a whole bag organised in one purchase, at the lightest weight per litre here.
- Three cubes at 7.5, 5 and 2.5 litres, with individual weights of 68, 56 and 44 grams and dimensions given for each, so you can plan a bag before you pack it.
- See-through mesh windows with high-visibility interiors, so you can identify contents without opening anything.
- YKK two-way zippers, which is the only named zip brand in this comparison, and recycled materials meeting Bluesign criteria.
- These organise rather than compress, with no compression zip on any of the three.
- No fabric denier or weight is published, unlike the shell specification on the Peak Design.
- Mesh windows are a wear point and are the first thing to fail on a cube used hard.
- Warranty and repairs are offered but the terms are not stated on the product page.
Real compression and the best warranty here, with no dimensions to plan around.
Best for: Compression above all, from the brand that invented the category, if you can judge the size in person.
- A durable compression zipper that compacts clothing to fit more items into a small space, which is the whole point of a compression cube and which only two products here offer.
- Mesh-topped construction so rolled or folded clothing is visible without unpacking, in a structured shape that holds its form in a case.
- One hundred percent recycled water-resistant fabrics, backed by Eagle Creek's No Matter What warranty.
- No dimensions and no volumes are published for either cube in the set.
- Two cubes rather than three, in small and medium only, so a full bag needs more than one set.
- No weight, fabric denier or zip brand is specified.
- Eagle Creek notes the set is available in limited quantity.
Six litres, expandable, lifetime warranty, and that is the whole page.
Best for: Someone buying into the Cotopaxi range who is happy to judge it on the warranty.
- A lifetime warranty with repairs offered, which matches the strongest cover in this comparison.
- Expandable rather than fixed, so the cube adjusts to its contents.
- Offered in 6 and 12 litre sizes, so there is at least a capacity choice.
- The product description consists of a single sentence saying it is an expandable packing cube for organisation.
- No dimensions, no weight and no expanded volume are published, so the 6 litres describes only one of its two states.
- No fabric, no denier and no zip specification are given.
- Nothing is said about mesh, visibility or water resistance.

How we judged the field
Volume came first, and specifically whether it is published at all and whether it is published twice. A cube that compresses has two volumes, one full and one squeezed, and the difference between them is the entire argument for buying compression rather than organisation. One product here publishes both, one publishes a single volume per cube across three sizes, and two publish nothing useful.
After that, dimensions, which decide whether the cube fits your bag and which two of these four omit entirely. Then weight, which matters to anyone flying with a carry-on allowance and which only two makers give. Then the construction details that determine how long a cube survives being crammed into a case: the fabric and its denier, the zip and its brand, and whether there is mesh, since mesh panels are the usual failure point. And finally the features that change how you pack rather than how much you pack, chiefly visibility and any separation between clean and worn clothing, plus the warranty, which in this category is unusually generous across the board.
The Peak Design Packing Cube is the most completely documented product in this comparison and the only one that addresses the problem of a trip in progress. The specification is given for both states: 32 by 17 by 8 centimetres and 4.5 litres compressed, 32 by 17 by 17 centimetres and 9 litres expanded, with an expansion and compression zip to move between them and an example capacity of 10 t-shirts when expanded. It weighs 110 grams. The fabric is a 100 percent recycled weatherproof Versa Heal 70D ripstop which Peak Design says self-heals small punctures and abrasions with the rub of a finger, and the zips are number 5 UltraZips sewn with proprietary abrasion-resistant thread. The feature that justifies the price is the internal divider: it separates clean clothes from dirty, and each compartment expands and contracts as its contents change, so the cube stays usable as the balance shifts across a trip rather than leaving you with a half-empty clean side and an overstuffed dirty one. A lifetime warranty covers it. The costs are that cubes are sold individually at premium prices, so a full set is a significant outlay, and that self-healing applies to small punctures rather than to real tears.
The Matador Packing Cube Set 3-Pack is the best value here and publishes nearly as much as Peak Design does. Three cubes come in the set at 7.5, 5 and 2.5 litres, with individual weights of 68, 56 and 44 grams and dimensions given for each, which means you can work out whether they fit your case and what they add to your allowance before ordering. That combination of a volume, a weight and a dimension for every piece is rarer in this category than it should be. The cubes have see-through mesh windows backed by high-visibility interiors, so you can identify contents at a glance rather than opening each one, and the zips are YKK two-way, which is the only zip brand named by anyone in this comparison. The materials contain recycled content meeting Bluesign criteria. What you do not get is compression: these organise, and there is no second zip to pull the walls in, so they will not reduce the volume your clothes already occupy. Matador also does not publish a fabric denier, and the mesh windows, useful as they are, are the component most likely to fail first.
The Eagle Creek Pack-It Reveal Compression Cube Set comes from the brand that effectively created this category and it does the compression job properly. The set pairs a small and a medium cube, each mesh-topped so rolled or folded clothing and accessories are visible without unpacking, in a structured construction that holds its shape inside a case. The compression is genuine: a durable compression zipper compacts the clothing to fit more items into a smaller space, which is the feature that actually creates room in a suitcase rather than merely tidying it. The fabrics are 100 percent recycled and water-resistant, and the whole thing sits behind Eagle Creek’s No Matter What warranty, which is among the strongest guarantees in luggage. What stops it being a straightforward recommendation is that Eagle Creek publishes no dimensions and no volumes for either cube, which for a product whose entire function is managing space is a strange omission, and means you cannot check it against your bag without buying it. There is also no weight, no fabric denier and no zip brand, only two cubes rather than three, and a note that the set is available in limited quantity.
The Cotopaxi Cubo 6L is the skip, and the entry is short because the page is short. The complete product description reads that these are expandable packing cubes for dialed organization. That is it. Cotopaxi offers a lifetime warranty with repairs, which is genuinely among the best cover in this comparison and is a real reason to trust the brand, and the cube is expandable rather than fixed, with a 6 litre and a 12 litre version available. Beyond that there is nothing to evaluate. There are no dimensions, so you cannot tell whether it fits your case. There is no weight. The 6 litres presumably describes one state of an expandable product, and the expanded volume is not given, which makes the headline figure half a specification. There is no fabric named and no denier, no zip brand, and nothing said about mesh panels, visibility or water resistance. Three competitors at comparable money publish between four and ten of those things, and one of them publishes all of them.
Peak Design Packing Cube, Medium vs Matador Packing Cube Set 3-Pack: which should you buy?
Peak Design against Matador is a choice between the best cube and the best set. Peak Design publishes everything: both volumes, both sets of dimensions, the weight, the fabric down to its denier and its self-healing property, the zip and the thread, and the lifetime warranty. Its internal divider separating clean clothes from dirty, with each side expanding independently, is the only feature in this comparison that solves a problem specific to being mid-trip rather than mid-pack. And it compresses, which Matador does not.
Matador gives you three cubes for less than the price of one Peak Design, at 7.5, 5 and 2.5 litres, each with a published volume, weight and dimension, plus mesh windows and high-visibility interiors that make finding things faster than any amount of compression does. At 68, 56 and 44 grams they are also the lightest per litre here by a wide margin. Buy the Peak Design if you travel constantly, want compression, and value the clean-dirty divider. Buy the Matador set if you want a whole bag organised in one purchase and would rather carry less.
What to look for
- Volume published twice on a compression cube: full and compressed, because the difference is the entire reason to buy compression.
- Dimensions in centimetres: measure your case first, since a cube an inch too long wastes more space than it saves.
- Weight per cube: trivial in a checked bag and not trivial in a strict carry-on allowance, and only half of these makers publish it.
- Mesh windows or a mesh top: the fastest way to find something, and also the component most likely to tear.
- A named zip: YKK or a specified size and thread, since the zip is what fails on a cube that gets crammed.
- A clean and dirty divider: the one feature here aimed at the middle of a trip rather than the start of it.
Our final take
Packing cubes split into the ones that organise and the ones that make room, and the good makers tell you which they are with a number. The Peak Design Packing Cube is the one to buy: 4.5 litres compressed and 9 expanded with dimensions for both, 110 grams, a self-healing recycled ripstop shell, an internal divider that keeps worn clothes away from clean ones, and a lifetime warranty. The Matador 3-Pack is the smarter purchase for most people, with three sizes, a volume, weight and dimension published for each, mesh windows and YKK zips, at a fraction of the cost. The Eagle Creek set compresses properly and carries the best warranty in luggage, and will not tell you how big it is. And a packing cube whose entire description is that it is a packing cube is asking you to buy the logo.
Questions, answered
Do packing cubes actually save space?
Only the compressing ones do. A plain cube organises clothes into a box and takes up roughly the space those clothes already occupied, plus the fabric. A compression cube has a second zip that pulls the walls in and squeezes air out, and that genuinely reduces volume, which is why Eagle Creek and Peak Design both build one in. If you want to fit more in a case, buy compression. If you want to find things without unpacking, any cube will do and the lighter ones are better.
How much weight do cubes add?
Less than most people assume, and it is still worth knowing when you are near an airline limit. Matador publishes 68, 56 and 44 grams for its three cubes, so a full set is under 170 grams, and Peak Design's medium is 110 grams on its own. Nobody else here publishes a weight at all. Across a set of four or five cubes you are adding perhaps 300 grams, which is negligible against a checked bag and not against a strict carry-on allowance.
What size cubes do I need?
Match them to the compartments in your bag rather than to your clothes. The usual approach is one large cube for bulky items such as jumpers, one medium for shirts and trousers, and a small for underwear and socks, which is exactly the 7.5, 5 and 2.5 litre split Matador ships. Measure the internal dimensions of your case first, because a cube an inch too long wastes more space than it saves. This is why publishing dimensions matters and why two of these four not doing so is a real problem.
Mesh tops or solid fabric?
Mesh lets you see what is inside without opening the cube, which is the single biggest day-to-day convenience, and it also lets clothes breathe, which matters if anything went in slightly damp. Solid fabric protects better against spills and abrasion inside a bag, and it is the stronger construction. Matador uses mesh windows with a high-visibility interior lining and Eagle Creek uses a mesh top; Peak Design does not describe mesh at all. Mesh panels are also the part that tears first, so treat them as the wear point.
Is a clean and dirty divider worth having?
On a trip of more than a couple of nights, yes, and Peak Design is the only maker here offering one. The alternative is either a separate laundry bag, which is another item to carry and to lose, or putting worn clothes back among the clean ones. Peak Design's divider also lets each side expand and contract independently, so the cube stays full as the balance shifts from clean to dirty across the trip. It is the most genuinely thought-through feature in this comparison.
