Says which set size suits which bag
Aerotrunk Compression packing cubes, 6-pack
The only set on this shelf to say which pack size suits which bag — and the only one whose own bullet claims 50 per cent more space and twice as much in the same breath.
One sentence here is more useful than most of this shelf: two cubes for a backpack, four for a carry-on, six for checked luggage. Nobody else bothers, and it addresses the real mistake buyers make, which is buying ten cubes and filling four — an empty cube is a cube holding air. The set is sold in all three sizes, so the advice can actually be followed.
The construction is named rather than praised. Nylon twill with a breathable mesh top panel, a double zipper compression design — which is the second track this shelf’s buying tip asks you to look for, and which four of the nine sets in the American half of this hub now have. The suggestion that the cubes go straight from the case into a hotel drawer is the right way to use them, and the reduced-creasing claim is fair for clothes held still rather than sliding about.
The arithmetic is not fair. The second bullet is headed “PACK TWICE AS MUCH” and its text says “up to 50% additional packing space”. Fifty per cent more is one and a half times; the heading overstates the maker’s own figure by a third. On this shelf the best-specified compression set publishes a before and after — four inches of thickness down to one — and its 75 per cent headline is exactly what that gives, which is what a claim looks like when the numbers are allowed to agree.
The other reservation is the price against the contents. This is the most expensive set on this shelf by a wide margin, six times the cheapest here, and it is six cubes and nothing else: no shoe bag, no laundry bag, no toiletry bag, where the ten-piece sets in the middle of this shelf include three or four of those for a third of the money. There is no cube dimension for any size, which puts it with eight of the nine sets here, and no fabric weight or denier to stand behind the nylon twill — one set on this shelf publishes 300D.

What travelers ask
Fifty per cent more, or twice as much?
The bullet says both, in the same two sentences, and they are different claims. Its heading is "PACK TWICE AS MUCH" and its text is "Get up to 50% additional packing space in your suitcase with our double zipper compression design". Fifty per cent more is one and a half times, not two — so the heading overstates the maker's own figure by a third. For comparison, the best-specified compression set on this shelf publishes a before and after thickness, four inches reduced to one, and its headline claim of 75 per cent is exactly what that arithmetic gives.
Why is a recommendation per bag worth something?
Because most people buy too many cubes and use half. Two for a backpack, four for a carry-on, six for checked luggage is the only guidance of its kind on this shelf, and it is the right shape of advice: a cube that does not get filled is a cube taking up space as air. The ten-piece sets in the middle of this shelf cost a third of this and come with bags for shoes, laundry and toiletries as well — which is a different proposition, and one this listing is quietly arguing against.
Is it worth six times the cheapest set here?
Only for the fabric and the compression, because nothing else is included. Six cubes with a second zip and a mesh top, in nylon twill, against a nine-piece set at a third of the price that has graduated compression cubes and a garment bag, or an eight-piece set at a sixth with no compression at all. What this page does not publish is the one figure that would justify the fabric claim — a weight or a denier, which one set on this shelf gives as 300D — or a single cube dimension.
