Insulation thickness and lid discipline, not the liter figure · review
A 30 liter passive box on wheels with a trolley handle and two lid-mounted ice packs, whose only stated cooling condition is the phrase "typical summer conditions".
A 30 liter rigid passive cooler on wheels, with an extendable trolley handle, two reusable ice packs that fix into the lid, a tight-closing lid and a smooth wipe-clean interior.
Alone in this hub, this box does not have to be lifted. On a campsite path or a beach that is a genuine difference, and it is the reason to look at this listing rather than at a 30 liter bag.
The two ice packs are stated to fix securely in the lid, so cold falls through the load rather than sitting under it. That is the same arrangement as the four-pack box in this hub, with half the packs.
No retention figure. Not one number, anywhere.
No insulating material. The word passive is stated; nothing behind it is.
No conditions, beyond the phrase “typical summer conditions”, which names a season and nothing measurable.
No drain, no empty weight, no gasket described on the tight-closing lid.
Wheeled boxes are heavier than the same volume in plastic without wheels, and this listing does not say what it weighs. If it has to go up steps as well as along a path, that is the figure you would want and it is not here.
On October 27, 2026 the reference had no Amazon.com price: Subcold is a British brand sold mainly in Europe, where it was listed at about €90 on Amazon.de. The listing groups a 28 L and a 30 L version, so check which size is selected before ordering.

The listing does not say. It is the only phrase in this hub that gestures at conditions at all, and it carries no temperature, no fill ratio and no duration. A named setting with no numbers in it is not a measurement, and this page treats it as unstated.
The listing states 30 liters and does not qualify it for the wheel housings. What wheels do change is how a full box travels — over grass and sand a trolley handle is worth more than a strap, and over a curb it is worth less than a handle you can lift with.
No. Not published on the listing — the box is stated passive with a tight-closing lid, and no insulating material is named. What the listing does publish instead is the box type: Rigid passive cooler on wheels — stated explicitly as passive, with a telescopic trolley handle.
8.4/ 10
The one you do not carry. It states its capacity, its wheels and its handle, and it will not tell you what it is insulated with or for how long.
A campsite pitch or a beach you can wheel to, where 30 liters never has to be lifted far.

A folding insulated shopping basket with an aluminum frame and a stated 66 lb (30 kg) load, and the only listing in this hub that publishes no capacity in liters at all.
Best for: Carrying a full grocery run from car to table, where the frame and the handles do more work than the cooling does.
Collapsible rigid box · 39 L, the largest on this shelf · EPP foam, 0.028 conductivity stated · 24 h cold and 12 h warm · buckle lid the maker says leaves gaps · no drain · no thickness
The largest capacity on this shelf at 39 liters, and the only listing anywhere here to publish a thermal conductivity figure — on a box whose maker says in its own last sentence that the lid leaves gaps.
Best for: A car boot where the box has to fold flat between trips and volume matters more than the seal
≈ $40

The only cooler on this shelf carried on both shoulders, and the several of the four listings anywhere here that publish an empty weight — 1.65 pounds, with six pockets and a leakproof liner.
Best for: A walk-in pitch or a cycle ride, where the cold has to travel on your back and not in your hand
≈ $25
