Packing cubes save space, not weight, so a tightly packed bag can still go over an airline weight limit. For most trips the answer is a mixed-size compression set matched to your bag: light ripstop cubes for a carry-on, a bigger, sturdier set for a checked suitcase.
Our picks
Aerotrunk Ultralight Compression Packing Cubes
Ultralight compression cubes that squeeze the most out of a carry-on on multi-stop trips where every bit of space counts.
Gonex Compression Packing Cubes 4-Piece
A light ripstop compression set, about 11.8 oz in all, that gets a week of clothes into a carry-on.
BAGSMART Compression Packing Cubes 8-Piece Set
Mixed compression sizes plus spare drawstring bags, a good set if you switch between carry-on and checked bags.
EPICKA TripCozy Compression Packing Cubes 6-Set
Tough 420D cubes built for frequent checked-bag trips, but at about 2 lb the set is too heavy for a carry-on.
OlarHike 10-Set Compression Packing Cubes
Four compression cubes plus extra bags and a garment bag, enough to get a whole family suitcase under control.
Amazon Essentials 4-Piece Small Packing Cubes
Four small cubes for socks, underwear and tees, the easy way to try packing cubes before you commit to a bigger set.
OlarHike 10-Piece Packing Cube Set
Six plain cubes plus shoe, laundry and toiletry bags that sort a whole suitcase, no compression needed.
Nite Ize RunOff Waterproof Packing Cube
A small waterproof cube that keeps a wet swimsuit or leaky toiletries away from everything else on beach trips and cruises.
CALACH XL Compression Packing Cubes 2-Pack
Two XL compression cubes that handle sweaters and jackets in a checked bag, but with no small sizes most people are better off with a mixed set.
What makes a good packing cube?
Get mixed sizes. Small cubes take socks and underwear, big ones take shirts and trousers. A set with only one size leaves the rest of your bag loose, which defeats the point.
The second zipper is what actually saves space. Close the cube, then run the compression track to squeeze it flatter. Mesh tops are a nice bonus, since you can see what's inside without opening every cube.
How do you choose packing cubes?
Flying carry-on only? Keep the cubes light. The ultralight Aerotrunk cubes barely register, and the Gonex set is about 11.8 oz in all. The EPICKA 420D set weighs about 2 lb on its own, which is a lot to give away before you've packed a shirt.
Checking a bag or packing for the family is different. Go big. Sets of eight to ten pieces cover a whole suitcase, and some throw in shoe, laundry and garment bags.
Compression or plain cubes?
Plain cubes organize. Compression cubes organize and shrink. If your bag already zips shut without a fight, keep it simple and get a plain set like the Amazon Essentials cubes, which cost less.
Trying to get a week of clothes into a carry-on? Then pay for compression. It's the part that does the work.
Which packing cube features aren't worth it?
Short trip, small bag, two or three cubes. That's it. A ten-piece set just adds weight you carry for nothing.
And don't overdo the squeeze. Compression saves volume, not weight, so a packed-tight bag can still go over an airline weight limit. Stuff the cubes too full and they're hard to close, and your bag turns into a dense brick.
Questions people ask
Are packing cubes worth it?
For most people, yes. You find things without unpacking everything, your clothes stay sorted, and compression cubes free up real space in a small bag.
Do compression packing cubes really save space?
Yes, by volume. They squeeze clothes flatter, but the weight stays the same, so keep an eye on your airline's weight limit.
How many packing cubes do I need?
Two to four mixed sizes is plenty for a carry-on. A checked bag or family suitcase can take a bigger set of six to ten pieces.
Can you put wet clothes in packing cubes?
Not in regular mesh cubes. Use a waterproof one like the Nite Ize RunOff so a wet swimsuit stays away from your clean clothes.
