Insulation thickness and lid discipline, not the litre figure · review
A 30 litre folding bag carried three ways, with a five-layer PEVA-coated insulation, waterproof zips and a stated 24-plus hours behind no conditions at all.
The bottom line The bag to walk with: backpack straps, waterproof zips, five stated layers and a real account of what 30 litres holds. The hours are the usual empty promise.
A 30 litre folding cool bag with a stated five-layer insulation and a PEVA coating, waterproof zips, and three carry positions — backpack, shoulder or hand. Stated PVC-free, and stated to fold flat.
Most listings stop at the number. This one states 48 cans of 0.33 litres plus ice cubes, or eight 1.5 litre bottles. That is the translation the litre figure needs, and it is the clearest one in this hub.
A layer count is more than most listings here give. It is not a thickness, and only one bag in this hub publishes one of those. Read five layers as a construction claim, not as a measurement.
Open-ended, and unaccompanied. No fill ratio, no ambient temperature, no statement of how much ice. The hub is unanimous on this: not one of the nine boxes publishes its conditions.
No drain — the interior wipes out with a cloth instead. No empty weight, which on a bag meant to be worn is the figure you feel first.
Backpack straps and 30 litres of chilled food is a real load. The bag does not tell you what it weighs empty, so weigh what you plan to put in it before deciding how far you will carry it.
Selling between 20 € and 27 € across the German, French and Spanish Amazon stores when this page was checked.
The Italian Amazon price sits more than 1.6× above the cheapest store. That gap usually means a reshipper rather than a local seller, so that listing is kept out of the range above.
Catalogued on the American and British Amazon stores with nobody selling it: the reference is there, the offer is not.

That is how it is written, and the listing gives nothing else — no fill ratio, no ambient temperature, no ice quantity. An open-ended figure with no conditions behind it is the weakest form of this claim, and this hub is full of the stronger-looking version of the same silence.
The maker states up to 48 cans of 0.33 litres plus ice cubes, or eight 1.5 litre bottles. That is the most useful translation of a litre figure anywhere in this hub, and it is worth reading as a maximum rather than a working load.
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.
≈ 20 €
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.
