Insulation thickness and lid discipline, not the liter figure · review
A folding 30 L cooler bag that carries as a backpack, a shoulder bag or by hand, with five-layer insulation, a PEVA lining and waterproof zips. Its Amazon.com listing had no offer, and a title in German.
On October 26, 2026, the Amazon.com page for this bag (B0BYDBDDXK) had no seller, and its title was in German. It is sold on the German, French and Spanish Amazon stores; the details below come from those listings.
A folding 30 L cooler bag with five-layer insulation, a PEVA lining and waterproof zips; 24-plus hours of cold stated; room for 48 cans of 0.33 L with ice or eight 1.5 L bottles; three ways to carry, on the back, over the shoulder or by hand; PVC-free materials; and a body that folds flat. The Spanish page names 8 mm of insulation. Amazon records the bag at about 2.2 lb (1,020 g) and 15 × 9.4 × 12.6 in.
No ice quantity, fill level or outside temperature is given, so the figure cannot be compared with another bag’s. Soft bags with 8 mm of foam are day bags.

Not on Amazon.com at the moment: on October 26, 2026 the listing for B0BYDBDDXK had no seller, and its title was in German. The closest cooler backpack on our shelf sold there is the Baglher 25 L at $24.99.
The European listings say 24 hours or more, without saying how much ice or how warm it was. The Italian listing adds that ice or ice packs are needed. Pre-chill the drinks and pack ice packs on the bottom and on top.
The listings give 48 cans of 0.33 L (about 11 oz) with ice, or eight 1.5 L bottles. The outer size, 15 × 9.4 × 12.6 in, works out at about 29 L before the walls are taken off.

Soft folding basket · 15 × 9.4 × 9.8 in (38 × 24 × 25 cm) open · heat-sealed lining · zip closure · 66 lb (30 kg) stated load · no liter figure published
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
