The carry-on that didn’t close — until it did
Porto airport, 5am, gate already boarding. My bag would not zip. I was doing the thing everyone does — kneeling on it, swearing quietly, pulling the zip a centimetre at a time — when the woman next to me, watching far too closely, said: “You need cubes.” She unzipped her own identical carry-on and it was a grid of neat little blocks, like a printer’s tray. Mine looked like a tumble dryer had exploded.
She wasn’t wrong, and that’s the whole pitch for the best packing cubes: they turn the panicked airport kneel into a bag that just closes. I’d resisted them for years — they felt like the kind of thing organized people bought to feel organized. Then I tried a cheap set on the next trip and packed the same amount of stuff into noticeably less space, found my socks without excavating, and pulled three cubes straight into a hotel drawer without unpacking a thing.
You probably don’t need them. People have folded shirts into suitcases since suitcases existed. But if your bag never quite closes, or you live out of it for a week and hate the daily rummage, the right set fixes both for less than the cost of one airport sandwich. By the end of this you’ll know which of the five below to buy — and it comes down almost entirely to whether you’re fighting for carry-on space or just want to stop the chaos.
The best value compression set going. A double-zip pulls the air out so a week of clothes shrinks to a few inches thick, and you get eight pieces — cubes plus a shoe and laundry bag — for roughly the price of one branded cube. The fabric is thin and the zips aren’t lifetime kit, but for the money nothing beats it.

Here’s the honest fork in the road, and it decides everything else. Standard cubes are fabric boxes with a single zip — they keep your bag tidy and your clothes from sliding around, but they don’t make anything smaller. Compression cubes add a second zipper that squashes the packed cube flatter, squeezing the air out of bulky stuff. That’s the version that actually frees up room.
Match the row to your trip and you’ve basically chosen.
| Your trip | Buy this | Type | Why |
|---|---|---|---|
| Carry-on only, tight on space | Bagail 8-Set | Compression | Most pieces for the money; flattens a week of clothes |
| Carry-on, want matched sizes | Gonex 4-Piece | Compression | Clean graduated cubes, up to ~30% space back |
| One set to last years | Eagle Creek Pack-It Reveal | Standard | Recycled fabric, self-repairing zips, huge mesh window |
| First time using cubes | Veken 6-Set | Standard | Cheap, light, see-through — zero learning curve |
| Standard carry-on, no fuss | TravelWise 5-Piece | Standard | Sized to slot into a cabin bag, durable ripstop |
The trap I fell into first: buying the biggest, most-pieces compression set and assuming more cubes meant more packed. It doesn’t. You end up splitting the same clothes across more bags. Which is exactly why the size mix matters more than the count — more on that below.
How I actually pack a week into a carry-on
Back to Porto. After that flight I went home and ran an experiment most people never bother with: I packed the same clothes twice, once loose and once in cubes, into the same 40-litre cabin bag. Loose, the lid bulged and I sat on it. In cubes — large cube for tops and trousers rolled, medium for underwear and socks, a small flat pouch for cables and the charger — the lid shut with room to spare, and I could lift all my clothes out in three grabs.
Two things I learned the hard way. One: roll, don’t fold, inside the cube. Rolled clothes fill the corners and crease less, and a compression cube only earns its keep if it’s full before you zip it flat. Two: don’t pack the extra-large cube. Every set seems to include one, and it’s a trap — it’s hard to fit in a carry-on and it quietly gives you permission to bring more than you’ll wear. I leave mine at home.
Bagail 8-Set Compression — the value champion
This is the set I hand to friends who say cubes are a rip-off. Eight pieces — graduated cubes plus a shoe bag and laundry bag — with a double-zip that genuinely flattens a packed cube. The fabric is thin and the zippers aren’t going to outlive you, but for what it costs, nothing else gets close on value. If you want to try compression without spending real money, start here.
Eagle Creek Pack-It Reveal — the one that lasts
The splurge, and the set I’ve owned longest. Recycled, bluesign-certified fabric, self-repairing #5 zips that shrug off being yanked at 5am, and a big mesh window so you can spot the right shirt without unpacking the cube. It’s standard, not compression, so it organizes rather than shrinks — but if you travel often and hate replacing gear, this is the buy-once option that’s still going seasons later.
Veken 6-Set — the beginner’s set
The one I’d give someone who’s never used cubes. Four graduated cubes in see-through mesh-topped twill, plus a shoe bag and a generous laundry bag, all light and cheap. No compression, nothing to learn — you just fill them and go. The mesh top means you can see what’s inside without opening anything, which is half the appeal of cubes in the first place.
Gonex 4-Piece Compression — for a tidy suitcase
If the Bagail’s eight mismatched pieces feel chaotic, this is the grown-up alternative: four expandable cubes in clean graduated sizes (XL/L/M/S) that zip flat to claw back up to a third of your space. Water-repellent ripstop, a tidier look, and sizes that actually nest into a suitcase. The pick when you want compression and order.
TravelWise 5-Piece — the dependable middle
A no-drama five-cube set — one small, two medium, two large — in light ripstop nylon with mesh panels and two-way zips. It’s not the cheapest or the toughest, but the sizing slots neatly into a carry-on and it does exactly what cubes should without fuss. The safe middle ground between bargain and premium.
How we picked
We weighted the things that matter on an actual trip: whether compression cubes really flatten (not just look like they do), zipper quality (the first thing to fail), how the sizes fit a standard carry-on, mesh visibility, and honest value for money.

Frequently Asked Questions
Do packing cubes actually save space?
Standard cubes don’t save space on their own — they organize it and stop clothes shifting, which makes a bag easier to pack tightly. Compression cubes do save space: a second zipper squeezes the air out, typically reclaiming 20-30% of the volume of bulky items like jumpers and jackets. For a small carry-on, compression is the version worth buying.
Are compression packing cubes better than regular ones?
For maximizing space in a small bag, yes. Compression cubes shrink bulky clothes and are ideal for carry-on-only trips. Regular cubes are lighter, cheaper, and quicker to pack, and they’re plenty for a checked bag where space isn’t tight. Many travelers carry both: compression for clothes, a standard mesh cube for cables and toiletries.
What size packing cubes should I buy?
Most sets come in graduated sizes and that mix works well: large cubes for tops and trousers, medium for underwear and socks, small for chargers and toiletries. For a carry-on, skip the extra-large cube — it’s hard to fit and tempts you to overpack. One large, one medium and one small per person covers a week comfortably.
How many packing cubes do I need for a carry-on?
Three to four cubes per person is the sweet spot for a carry-on: one large for clothes, one medium for layers, one small for underwear and socks, plus a flat pouch for tech and toiletries. More than that and you’re usually splitting the same clothes across cubes rather than fitting more in.
Can you wash packing cubes?
Yes. Most polyester and nylon cubes are fine on a cold, gentle machine wash inside a laundry bag, then air-dried — don’t tumble dry, as heat can warp the zips and coatings. Spot-clean compression cubes instead if you can, since repeated washing wears the second zipper faster than the rest of the cube.
The bottom line
Decide compression or standard first, then match the set to your trip: Bagail or Gonex if you’re fighting for carry-on space, Eagle Creek if you want one set for years, Veken or TravelWise if you just want the chaos to stop. Mine cost less than that airport sandwich and my bag has closed on the first try ever since — easiest packing upgrade I’ve made.
