Insulation thickness and lid discipline, not the liter figure · review
A cheap soft cool bag with 8 mm (0.31 in) of foam and a 12-hour cold claim. It sells in Europe; on Amazon.com the same listing has no offer, so this page points to bags you can buy in the US.
On October 25, 2026, the Amazon.com page for this listing (B0CFL1XLDC) showed a “Thermal Bag 30L” with no seller offering it. The bag is sold on the German, French, Italian and Spanish Amazon stores, and the construction details below come from those listings.
A soft, passive cool bag that folds flat when empty: a 600D Oxford polyester shell, 8 mm (0.31 in) of EPE foam, and a PEVA lining that the maker calls leakproof. It has a padded handle, an adjustable shoulder strap that unclips, a front pocket and two side pockets. The Spanish listing names a zip closure.
EPE (expanded polyethylene) is the closed-cell foam used in most budget soft coolers. At 8 mm (0.31 in) it is a day-bag wall. Rigid boxes on this shelf go much thicker: the Pinnacle lunch box publishes 20 mm (0.79 in) of polyurethane foam.
The French and Italian listings give 40 × 25 × 29 cm (15.7 × 9.8 × 11.4 in) outside. That is about 29 liters of outer volume, and the walls take some of it. The German listing says 45 cm long, which would give 33 liters outside, still not 33 inside. Plan on a little under 30 liters, and check bottle heights: a 2-liter soda bottle will not stand up in 11.4 in.
Twelve hours cold and four to six hours hot on the Amazon.com listing, 14 hours in the German title. None of them says how much ice, how full, or how warm the air was, so the figure cannot be set against another bag’s. Pre-chill the food and pack ice packs on the bottom and on top.

| Box type | Soft folding insulated bag; passive, with no power connection |
|---|---|
| Capacity | 30 L on the Amazon.com listing, 33 L in the German, French and Italian titles. The published outer size of 15.7 × 9.8 × 11.4 in (40 × 25 × 29 cm) encloses about 29 L, so the usable space is below both figures |

Not on Amazon.com at the moment. On October 25, 2026 the listing for B0CFL1XLDC showed a 30 L thermal bag with no seller. The closest soft bag on our shelf that is sold there is the Baglher 25 L backpack, at $24.99 that day.
The Amazon.com listing says 12 hours cold and 4 to 6 hours hot; the German title says 14 hours. No ice quantity or outside temperature is given. With 8 mm (0.31 in) of foam, count on a day out with pre-chilled food and ice packs, not a weekend.
No. The published outer size, 15.7 × 9.8 × 11.4 in (40 × 25 × 29 cm), works out at about 29 L before the walls are taken off. A 2-liter soda bottle, about 13 in tall, will not stand upright in 11.4 in; it lies across the bottom.
7.2/ 10
A sensible cheap day bag whose foam and lining are actually named, but it cannot be bought on Amazon.com today and its liter figure is generous. US buyers should start with the Baglher backpack or the Quiksilver soft cooler.
A day picnic or a grocery run, for someone shopping on a European Amazon store. In the US, look at the alternatives below.
Amazon reports what buyers took in the month before this page was last checked: at least 100.
The figure is a floor, rounded by Amazon, and read through Keepa — it says what buyers picked, not what a maker claims.
Specifications: the manufacturer sheet for camping and hiking gear and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.

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
