Insulation thickness and lid discipline, not the liter figure · review
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.
A soft insulated cooler backpack, 25 liters, 30 cans.
BAGLHER states insulation material and a leak-proof liner working together to prevent leaks and keep food hot or cold for 16 hours; external dimensions of 13 × 8 × 17 in, a weight of 1.65 lb and a 25 L volume holding up to 30 cans of 330 ml; that adding ice packs can enhance cooling performance; one main compartment, two large front zip pockets, two side mesh pockets, one mesh pocket in the lid and a bottle opener on the strap; and a durable fabric shell.
No insulation named. No thickness. No conditions. No drain.
Two straps, on a shelf of handles.
Three European bags on this shelf offer a shoulder strap. None is a two-strap pack, and the rigid boxes have swing handles or a trolley.
One point six five pounds empty — about 749 g (26.4 oz) — which is the lighter of the only two empty weights published anywhere on this shelf.
The condition stated is the absence of one.
Two bullets give 16 hours, hot or cold. A third says separately that adding ice packs can enhance cooling performance.
So the figure is quoted for an unchilled bag, and the ice is an improvement on it. That is a clearer condition than most listings here manage, and it is also the shortest claim among the American ones.
The first figure this shelf’s introduction asks for.
Several of the four listings on this shelf name what is in their walls: EPP foam, 20 mm (0.79 in) polyurethane, five-layer PEVA, aluminum foil over 8 mm (0.31 in) EPE, and one trade name.
This one says insulation material, and leaves it there. No thickness either.
What is published instead is the carry and the pockets — six of them, which is the most on this shelf.
The American Amazon store was listing it at about $25 at the time of writing.

| Box type | A soft insulated backpack — the only listing on this shelf carried on two shoulders. Three European bags here offer a shoulder strap; none is a two-strap pack |
|---|---|
| Capacity | 25 L — stated, with up to 30 cans of 330 ml, and external dimensions of 13 × 8 × 17 in. Those are the only external dimensions published by an American listing on this shelf |
| Insulation type | Not named. The listing states insulation material and a leak-proof liner working together, and does not say what either is made of. Several of the four listings on this shelf name their insulation; this is not one of them |
| Insulation thickness | Not published |
| Ice retention | 16 hours, for hot or cold — stated twice, with the note that adding ice packs can enhance cooling performance. It is the shortest claim among the American listings here, against 24 and 48 hours |
| Ice retention conditions | Not published — no fill ratio, no ambient temperature, no ice quantity. The 16 hours is quoted with no ice in the bag at all, since the listing treats ice packs as an optional addition |
| Closure and seal type | Zips — one main compartment, two large front zip pockets, two side mesh pockets, one mesh pocket in the lid. The liner is stated leak-proof; no gasket and no roll-top |
| Drain | Not published. No listing on this shelf publishes one, and on a bag with a leak-proof liner the melt water has nowhere to go but out through the zip |
| Carry arrangement | Two shoulder straps, with a bottle opener fitted to one of them. Six pockets in all, which is the most on this shelf |
| Empty weight | 1.65 lb — stated, about 749 g (26.4 oz). One of only two empty weights published on this shelf, and the lighter of the two; the European Kreher rigid box states 1.3 kg (2.9 lb) |

Without, as the page reads. The second and third bullets both state that food stays hot or cold for 16 hours, and the third adds separately that adding ice packs can enhance cooling performance — which puts the ice outside the claim rather than inside it. That is unusual and worth noticing, because this shelf's buying tip asks you to read the conditions beside any retention figure, and here the condition that is stated is the absence of ice. Sixteen hours is also the shortest claim among the American listings on this shelf, where two others claim 48 and one 24.
The listing does not say. It states that insulation material and a leak-proof liner inside work together, and that is the whole description — no foam named, no foil, no thickness. Several of the four listings on this shelf do name theirs: EPP foam, 20 mm (0.79 in) polyurethane, five-layer PEVA, aluminum foil over 8 mm (0.31 in) EPE, and a maker’s trade name. This shelf's introduction makes insulation type and thickness the first thing to compare, and on this listing neither figure exists, so what you are buying is the carry and the pockets.
Nowhere, which is the point of the leak-proof liner and also its limit. No listing on this shelf publishes a drain — all thirteen are silent on it, although this shelf's introduction asks for one you can reach — and on a backpack the consequence is sharper than on a box: the water sits in the bottom of the main compartment until you tip it out through the zip. Pack ice in bags rather than loose if you intend to carry this on your back for a day, and expect the emptying to be a two-handed job over a drain or a bush.
Close prices, same category: comparable camping gear. We keep only the specifications all of them publish, because a column with gaps compares nothing.
| Model | Price | Box type | Capacity | Insulation type | Insulation thickness |
|---|---|---|---|---|---|
| BAGLHER Cooler backpack, 25 L | $25 | A soft insulated backpack — the only listing on this shelf carried on two shoulders. Three European bags here offer a shoulder strap; none is a two-strap pack | 25 L — stated, with up to 30 cans of 330 ml, and external dimensions of 13 × 8 × 17 in. Those are the only external dimensions published by an American listing on this shelf | Not named. The listing states insulation material and a leak-proof liner working together, and does not say what either is made of. Several of the four listings on this shelf name their insulation; this is not one of them | Not published |
| Pinnacle PIB-450B | $24 | A rigid passive box with a flip-top lid — no power, no ice packs supplied. One of two rigid American boxes on this shelf | Published twice, and the two do not agree: the title says 4.5 to 11 liters, and the fourth bullet says this picnic cooler has a 4.5 liter capacity. Four point five liters is the smallest capacity published on this shelf; eleven would still be among the smallest | Polyurethane foam — named, with BPA-free materials stated for the shell | 20 mm (0.79 in) — stated. It is the thickest insulation published anywhere on this shelf, and one of only two thickness figures on it; the European Lifewit bag publishes 8 mm (0.31 in) of EPE |
| BRILLIRARE Collapsible 39 L ice chest | $40 | A collapsible rigid box — EPP foam walls that fold, stated to save up to 80 per cent of their space when packed down. It is the only folding rigid box on this shelf; the other rigid boxes here are fixed shells and the folding products are soft bags | 39 L — stated, given also as 10.3 US gallons and as 60 small bottles or jars. It is the largest capacity published on this shelf, above the 33 L soft bag and the 30 L group | EPP foam — expanded polypropylene, named, and described as owing its insulation to small bubbles in its structure, with a waterproof surface layer over it | Not published. In its place the listing gives a thermal conductivity coefficient of 0.028, which is the only conductivity figure published anywhere on this shelf. A conductivity tells you how well the material insulates; a thickness tells you how much of it there is, and without the second the first cannot be turned into a wall |
| Quiksilver QK-CB12-TPC | $50 | A soft box cooler — a structured bag that holds its shape, stated as a soft cooler rather than a rigid shell | 18 L — stated, with up to 24 cans plus ice. The liter figure and the can figure are both given, which half the listings on this shelf do not manage | Not named. The listing states advanced insulation technology and a high-performance thermal lining, and names no foam, foil or laminate | Not published |
A walk-in pitch or a cycle ride, where the cold has to travel on your back and not in your hand

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
Rigid passive box · 22 L (23 qt) · 10.8 × 17.5 × 15.1 in · four 15 oz (450 ml) ice packs in the lid · 40 h cold / 18 h warm stated · 2.4 lb · PU/PP
The longest cooling figure published by a European listing 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.
