Insulation thickness and lid discipline, not the litre figure · review
The only bag in this hub to publish an insulation thickness — 8 mm of EPE foam under an aluminium liner — and it publishes no retention figure at all.
The bottom line The listing in this hub that describes what it is made of instead of what it claims to do. On a shelf where every hours figure is unconditioned, that is the more useful page.
A 30 litre folding cool bag with a stated 1680D waterproof Oxford shell, an aluminium foil lining padded with 8 mm of EPE foam, a zip over a wide opening, a padded hand grip and a removable shoulder strap. Overall dimensions are stated at 40.5 × 26.5 × 31 cm.
This is the figure the category is decided on and this is the only listing in the hub that publishes it. 8 mm of EPE foam under a foil liner is a different product from a foil liner alone, and until a maker states the number there is no way to tell the two apart from a photograph.
The listing states the lining keeps food warm or cold and gives no hours at all. That is a strange omission on the one bag with a construction worth quoting. It is also, arguably, the more honest position: an hours figure quoted without a fill ratio or an ambient temperature is not a measurement, and every one in this hub is quoted that way.
No drain. No empty weight.
Check 31 cm of stated height against the tallest thing you carry. A 1.5 litre bottle stands up in that; a 2 litre bottle may not.

It also sells on the British Amazon store in the local currency, which the range above does not cover — that range counts euro stores and nothing else.
Nothing came back from the American Amazon store, so the buy link there opens a local search instead of a page that is not there.

Because it can be compared. Every hours figure in this hub is quoted without a fill ratio or an ambient temperature, so two of them cannot be set against each other. A stated foam thickness under a stated foil liner is a description of the thing itself, and this is the only listing here that gives one.
It is the denier of the outer fabric, stated by the maker and stated to be waterproof. A denier figure describes the yarn thickness of the shell, which is about abrasion and tearing rather than about cold, and no other cool box in this hub publishes one.
Soft folding basket · 38 × 24 × 25 cm open · heat-sealed lining · zip closure · 30 kg stated load · no litre figure published
A folding insulated shopping basket with an aluminium frame and a stated 30 kg load, and the only listing in this hub that publishes no capacity in litres at all.
Best for: Carrying a full shop from car to table, where the frame and the handles do more work than the cooling does.

Soft folding bag · 30 litres in the title, lunch bag in the bullets · over 12 h stated · isothermal lining, unnamed · no closure described
A folding cool bag whose title says 30 litres and whose bullets describe an office lunch bag five times over — the two halves of the listing do not agree, and this page reports both.
Best for: A packed lunch rather than a picnic, on the reading of this listing that its own bullets support.
≈ 25 €
Rigid passive box · 22 litres · 27.5 × 44.5 × 38.3 cm · four 450 ml ice packs built into the lid · 40 h cold and 18 h warm stated · PU/PP
The longest cooling figure published in this hub at 40 hours, and the listing itself says the number rests on the four ice packs built into its lid.
Best for: A weekend where the box is packed once and opened rarely, and the ice packs are frozen properly beforehand.
