The best packing cubes for a carry-on come down to four sets. They are Eagle Creek Pack-It Reveal, Monos Compressible, Away and BAGAIL Compression. Every price, size and material in this guide comes from the maker’s own product page, checked on the date at the bottom of this post.

I packed for a two-week move from Chicago to Southern California with a car full of boxes and one suitcase I actually had to carry. That trip is what sold me on packing cubes. It was not the tidiness, though that helps. It was watching a stuffed carry-on close on the first try instead of the third. The four sets below cover the decision most people are actually making. How much compression do you need, and how much will you pay for it?

What are the best packing cubes to buy?

Four things separate a cube set you keep using from one that dies in a closet. First, does it actually buy you volume, or only tidiness? Second, how much weight does it add to a bag already fighting an airline limit? Third, do the sizes match the way you divide clothes in real life? And fourth, does the fabric survive repeated stuffing?

So we compared the four sets on published specs rather than impressions. That means price, cube dimensions, set weight where the maker publishes it, fabric, and whether compression is a real mechanism or a marketing word. Where a maker does not publish a number, we say so instead of filling the gap.

Eagle Creek Pack-It Reveal Review

This is the set to start with if you own none. The XS/S/M set runs $59 and weighs 8.1 ounces in total, which is the lightest published figure in this group. Eagle Creek breaks that down by cube: 1.6 ounces for the XS, 2.5 for the S, 4 for the M. So the whole set costs you about half a pound of your carry-on allowance.

The sizes are 7.5 by 4.5 by 2.5 inches, 10 by 7 by 3, and 14 by 10 by 3. That maps neatly onto small items, folded tops, and bulkier layers. The fabric is 100% recycled 300D polyester with a poly mesh top, and Eagle Creek says it is made without the intentional use of PFAS. The mesh matters more than it sounds, because you can find one shirt without unzipping the whole cube.

• Pros: lightest published set weight here at 8.1 oz, recycled 300D fabric, mesh tops for visibility, angled zipper that lets you stack or roll
• Cons: these are not compression cubes, and Eagle Creek sells compression as a separate line, so the $59 does not buy you volume savings

Monos Compressible Packing Cubes Review

If the goal is fitting a long trip into one carry-on, this is the set that changes what fits. Monos sells it at $95. The set of four is the carry-on set; the set of six is sized for check-in luggage. Built-in compression zippers are the mechanism, and Monos states they compress height by up to 60%.

Read that claim carefully, though. It describes height, not total volume, and it is an upper bound rather than a typical result. Still, height is the dimension that decides whether a carry-on lid closes. The four-cube set measures 13 by 9.8 by 4.5 inches, 13 by 7.1 by 4.5, 10.2 by 8.3 by 4.5, and 9.8 by 4.3 by 4.5. The exterior is tear-resistant nylon twill, and the lining is 100% recycled polyester.

• Pros: real compression zippers rather than containment alone, up to 60% height reduction per Monos, recycled polyester lining, six-cube option for checked bags
• Cons: the most expensive set here at $95, nearly double the Away set, and the 60% figure is a maximum rather than a promise

Away Packing Cubes Review

The set of four costs $48, which makes it the cheapest of the three premium options, not the priciest. Away builds these from water-repellent nylon with a mesh panel on top. There are no compression zippers. Away describes the cubes as a mild compression system that works by keeping clothes tightly contained, and it sells dedicated compression cubes separately.

The real argument for this set is fit. Away states that one set of four fits its Carry-On suitcases, two sets fit its checked suitcases, and three fit The Trunk. The cubes run 10 by 4.1 by 8.25 inches, 10 by 4.1 by 4.3, 13 by 4.1 by 10, and 13 by 4.1 by 6.9. Notice that every cube is 4.1 inches deep, which is why they stack into a suitcase shell without leaving gaps.

• Pros: $48 for four cubes, uniform 4.1-inch depth that stacks cleanly, water-repellent nylon, mesh top, and a published fit for each Away case size
• Cons: no compression zippers, so it will not shrink a packed load the way Monos or BAGAIL will, and Away does not publish a set weight

BAGAIL Compression Cubes Review

Buy this set if you are not yet sure cubes are for you, or if you are outfitting a whole family. The four-piece full-cloth set is $19.99. A six-piece square mesh set is $29.99, and a five-piece square mesh set is $35.99. So one order can cover several travelers for less than a single premium set.

These are genuine zip compression cubes, which is unusual at this price. BAGAIL also sells ultralight versions in 30D Cordura, 40D and 70D mesh, and 70D nylon, if weight matters more than durability to you. The company does not publish a denier for the standard cloth-and-mesh cubes, so treat fabric comparisons against the premium sets as unknown rather than favourable.

• Pros: real compression at $19.99 for four, larger sets available cheaply, ultralight fabric options for travelers counting ounces
• Cons: no published denier or set weight for the standard cubes, and the fabric and zippers are the parts most likely to show wear first under heavy use

Which packing cubes are the best?

If you only own one set, get the Eagle Creek Pack-It Reveal. It is the most balanced across weight, fabric and price. Go with Monos if you are specifically trying to compress a long trip into a carry-on, and accept that you are paying $95 for a zipper mechanism. Choose Away if you already travel with Away luggage, because the published fit is the whole point and $48 is not a stretch. And grab BAGAIL if you want to find out whether cubes suit you before spending more.

One thing worth naming: only two of these four sets compress. So if you are buying cubes to make things fit, rather than to stay organised, Eagle Creek and Away are the wrong tools no matter how good they are.

Do packing cubes save space?

Compression cubes do. The zip designs from Monos and BAGAIL squeeze air out, and Monos puts the height reduction at up to 60%. Non-compression cubes work differently. Away and the base Eagle Creek set do not add space so much as organise what you already have. That still helps, because folded and contained clothes waste less room than loose ones. But the gain is smaller, and it disappears if you were already a tidy packer.

How many packing cubes do I need for a carry-on?

For most one-to-two-week trips, three or four cubes covers it. Use one for tops, one for bottoms, and one for underwear and socks. Then keep a small separate cube for anything you would rather not mix in with clothes. Past that, you are mostly carrying cubes rather than clothes, and each empty cube still weighs something.

For what goes inside the cubes, see the carry-on only packing list. For a bag to put them in, see the travel backpacks we compared. The cruise, beach and dog road trip lists cover other kinds of trips.

Carry On Luggage Size Limit

American Airlines caps a carry-on at 22 by 14 by 9 inches, including handles and wheels. That is the box every cube in this guide has to live inside. The largest cube here is the Monos six-set’s 16.9 by 12.2 by 4.5 inches, which is a checked-bag cube rather than a carry-on one.

Work backwards from depth instead of length. A hard-shell carry-on gives you roughly four inches of usable depth per side, which is exactly why Away sizes every cube at 4.1 inches and Monos at 4.5. A cube deeper than that either will not lie flat or forces the lid to bow. So if you are buying cubes for a specific suitcase, measure the shell before you measure the clothes.
