How we test: We own and travel with most of the gear we recommend and put it through real con weekends; the rest we vet with suiters we trust or draw from their first-hand reviews. Where you see photos of a unit in a review, those are our own or friend's and blog supporters.
These are the compression cubes that live in our own con bag, so this is a review of gear we have packed, unpacked, and re-packed across real trips rather than one we sized up from a listing. The set is two cubes: a small and a medium, both in a tough diamond-ripstop nylon with a perimeter compression zip.
Where we landed: the Thule set is the nicest-built pair of compression cubes we have used, and it earns its place for carrying folded clothes and soft con kit in a bag you want to stay organized. What it is not, and does not pretend to be, is a way to vacuum-flatten a whole bodysuit into a tight case. For that we still reach for vacuum bags. Buy this for organization and durability rather than for maximum squeeze.
The rule that governs all of this: compress the body, never the head. A head base takes a permanent set from pressure, and no amount of saved luggage space is worth that.
Do not buy these expecting vacuum-bag compression. They do not deliver it, and pretending otherwise is how people end up disappointed at the check-in scale. A vacuum bag flattens a bodysuit far more than any cube.
What this set does better than the cheap cubes is the part that actually matters over years of travel: it holds up. The fabric is a proper ripstop with a bound edge and a chunky main zip, where cheap cubes use tissue-thin nylon that frays at the corners after a few trips. Ours have been crushed under other bags in a checked case and have not snagged or split a seam. When a cube is the thing keeping your bag organized every trip, paying once for one that lasts is the honest value case.
The two-cube split is the other reason it stays in the bag. The medium takes the folded daytime clothes; the small takes soft kit, toiletries, or the odds and ends you want to reach without excavating the whole case. Each has its own grab loop, so pulling one out does not disturb the rest.

The pattern that works is one cube per thing. Folded clothes and the daytime outfit go in the medium; the small takes soft kit you want quickly. On a heavier trip we pair these with vacuum bags for the bulk suit parts and let the cubes do the clothes, so the case has both the hard squeeze and the tidy organization without either tool doing a job it is bad at.
The compression zip is genuinely useful once the cube is packed: fold, zip the lid, then run the second zip around to pull the stack flat. It is not a dramatic shrink, but it firms a soft pile into a stable brick that stacks and does not shift in transit.
On the return leg the difference from vacuum bags shows plainly. Everything you unpacked over a weekend goes back in at whatever hour you are packing, with just the zip and your hands. That convenience is the real reason a cube stays in the bag even when a vacuum bag is doing the heavy compression.
The same kind of gear we have tested ourselves. Read the verdict before you pick.
Best for: Organizing clothes and soft suit parts in a case, not maximum compression
Zip-down packing cubes that keep a case organized and give folded clothes and soft suit parts a modest squeeze with no pump. For real compression we reach for vacuum bags; these are the travel organizer.
For the build, yes; for the compression, no. The fabric and zips are a clear step up from generic cubes and have lasted us where thin ones frayed, which is the case for buying once. But if your priority is maximum compression or the most cubes for the money, a cheaper four-pack or a vacuum bag makes more sense.
No. Nothing that compresses should touch a head base. Pressure deforms foam and resin permanently, and the damage is a repair or a rebuild rather than an inconvenience. Heads travel uncompressed in a hard case.
Enough to firm a soft, folded pile into a stable, flat brick, not enough to rival a vacuum bag. Thule's own dimensions give the shape of it: the medium cube is about 5.9 in deep expanded and compresses toward roughly 1.25 in once packed and zipped. That is real, but it is a flatter, tidier stack rather than the dramatic volume loss a vacuum bag delivers. For shrinking a bodysuit, use vacuum bags.
Any compression flattens pile while it is held, and a vacuum bag holds it flatter for longer than a cube does. Whichever you use, un-compress on arrival and give the suit time to loft back before you wear it, rather than pulling it straight out and suiting up.
Usually not a whole suit plus clothes. The pair is sized for clothes and soft kit; for a full suit, pair them with vacuum bags for the body or add a third bag rather than overstuffing the medium.
They help you fit more inside a bag you already have. They do not shrink the bag, so the linear-inch and weight limits still apply exactly as before.
