Insulation thickness and lid discipline, not the litre figure · review
The largest stated capacity in this hub at 33 litres, with a 14 hour cooling figure and no word anywhere about what the insulation is made of.
The bottom line The biggest stated volume here, with a figure on the front and nothing behind it. Buy it for the litres and the strap, not for the cooling claim.
A folding soft cool bag stated at 33 litres, with external dimensions of approximately 45 × 25 × 29 cm, a fitted shoulder strap, outer and side pockets, and a stated 14 hours of cooling.
Capacity in litres is the figure this shelf sells on and it is not the figure that decides. This listing publishes dimensions alongside the litres, which is what lets you check whether a 1.5 litre bottle stands up inside rather than lies across the top.
Stated in the title, with no fill ratio, no ambient temperature and no ice quantity behind it. That is the standard silence in this hub — none of the nine boxes here publishes its conditions — and it means the 14 cannot be set against another bag’s 24.
No insulation named. Not foam, not foil, not a thickness. On a soft bag this is the single most useful thing to know and it is absent.
No closure described. A zip, a roll-top and an open top behave completely differently once the bag is full.
No drain, no empty weight.
This is a passive bag: it holds the cold you put in it and nothing more. Plan for ice packs, and remember that the litre figure includes the space they take.

It is not, and this listing is better placed than most to show why: it publishes external dimensions of roughly 45 × 25 × 29 cm beside the litre figure. A 1.5 litre bottle is about 30 cm tall, so measure against the depth rather than against the volume.
The listing does not say. There is no fill ratio, no ambient temperature and no statement of how much ice goes in. No cool box in this hub publishes those conditions, so treat every figure here, including this one, as a claim rather than a measurement.
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.
