The comfort rating, not the season name, describes your night · review
A hooded mummy bag that publishes a temperature range without saying which end is comfort, and gives neither a weight nor a packed size.
A hooded mummy bag suitable, the maker says, for temperatures from 8 °C (46 °F) to -5 °C (23 °F), a 300 GSM fill, an extra-insulated zip, a soft inner lining, polyester construction with a DWR water-repellent finish, an internal hook-and-loop pocket, coupling into a double, and a pillow in the box.
8 °C to -5 °C. Thirteen degrees, and neither end is named. On a bag described under a standard, one of those would be the comfort figure — the temperature at which a standard sleeper rests without curling up — and the other something else entirely.
Here they are simply the two ends of a claim. No standard is named, so neither is a laboratory value, and there is nothing published that says which end to plan on.
The zip baffle. A mummy bag’s zip is the longest cold bridge in it, and an insulated baffle behind the teeth is the fix. Naming it is worth something.
The DWR finish. Named as a treatment rather than described as water-repellent in general, which means it can be renewed when it stops beading.
Weight and packed size, both. On a bag with a 300 GSM fill and a pillow in the box, that is not a small omission — this is not a light bag, and nothing says how heavy it is.
Decide which end of the range you are buying for, and ask the seller for the weight if it has to go in a pack.

| Comfort rating | Not stated as a comfort figure — the maker publishes a range of 8 °C (46 °F) to -5 °C (23 °F) without saying which end is comfort, and names no standard |
|---|---|
| Limit rating | Not stated as a limit figure — the same unlabelled 8 °C (46 °F) to -5 °C (23 °F) range is all that is published |
| Standard quoted | None named — neither EN 13537 nor ISO 23537 appears in the listing |
| Fill power | Not published on the listing — fill power describes down, and this bag is stated as polyester |
| Fill weight | No weight published — the maker publishes 300 GSM, a fill density in grams per square meter |
| Down or synthetic | Synthetic — stated as polyester |
| Shell denier | Not published on the listing — a polyester outer with a DWR finish is named, with no yarn weight |
| Baffle construction | Not published on the listing — an extra-insulated zip baffle is named; the body construction is not |
| Packed size | Not published on the listing |
| Weight | Not published on the listing |

Because the two ends mean opposite things. If 8 °C (46 °F) is the comfort figure, this is a three-season bag; if -5 °C (23 °F) is, it is a winter one. Nothing in the listing says, and the difference is the whole purchase.
A durable water-repellent treatment on the outer face that makes drops bead and roll rather than soak in. It wears off with use and washing and can usually be renewed with a wash-in or spray-on product. It is not waterproofing, and it does not make the bag safe in rain.
No. Not stated as a comfort figure — the maker publishes a range of 8 °C (46 °F) to -5 °C (23 °F) without saying which end is comfort, and names no standard. What the listing does publish instead is the down or synthetic: Synthetic — stated as polyester.
7.8/ 10
Careful about its hardware and vague about its numbers. The zip baffle and the DWR finish are real details worth having; the temperature range, unlabelled and unstandardized, is not something to plan around.
Cooler-weather camping where the bag is driven to the pitch and a pillow in the box is worth having.

Mummy · 400 GSM synthetic · comfort +4 °C (39 °F) and limit -2 °C (28 °F) stated · 1.55 kg (3.4 lb) total · compression sack · no standard named
The only bag here to publish a comfort and a limit figure separately — and, like every other bag in this group, it names no standard behind them.
Best for: Three-season camping where a stated comfort and limit pair matters more than a published packed size.

A three-season mummy bag that publishes weight, packed size and fill density, and puts its comfort range at 15 °C (59 °F) to 20 °C (68 °F) with no standard behind it.
Best for: Spring to autumn trips where about 1300 g (45.9 oz) into a 35 × 25 cm (13.8 × 9.8 in) roll is the constraint that matters.
20 °F, no standard · 82 × 33 in · polyester shell, brushed tricot liner · no-snag zip
Five bullets, five facts and no padding: a 20 °F mummy bag of 82 by 33 inches with a drawstring hood, a brushed tricot liner and an anti-snag zip with contrasting webbing.
Best for: A straightforward cold-weather mummy bag with nothing to decode
