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.
The bottom line 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 unstandardised, is not something to plan around.
A hooded mummy bag suitable, the maker says, for temperatures from 8 °C to -5 °C, 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.

Because the two ends mean opposite things. If 8 °C is the comfort figure, this is a three-season bag; if -5 °C 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.
Mummy · 400 GSM synthetic · comfort +4 °C and limit -2 °C stated · 1.55 kg total · compression sack · no standard named
