The comfort rating, not the season name, describes your night · review
A large mummy bag that names a comfort temperature of around 0 °C (0 °F), publishes weight, packed size and a full cut, and names no standard behind the figure.
A lying area of 230 × 82 × 55 cm (90.6 × 32.3 × 21.7 in), a weight of 1900 g (67 oz), a packed size of 24 × 30 cm (9.4 × 11.8 in) in a compression sack, a 350 GSM double-layer fill, a Pongee polyester lining, a comfort temperature given as around 0 °C (0 °F), a breathable rustle-free outer with a PFC-free water-repellent coating, and a double anti-snag band at the zip. The title carries -23 °C (-9 °F) and -5 °C (23 °F).
The bullet says it plainly: the comfort temperature for warm nights is around 0 °C (0 °F), at a fill of 350 GSM. That is a comfort figure, named as such, attached to a fill density. It is the most complete temperature claim of any bag in this group.
The title’s -23 °C (-9 °F) and -5 °C (23 °F) are a different matter. Neither is labeled, both sit far below the comfort figure, and no standard is named for any of the three. Under EN 13537 or ISO 23537 the figures would come from a heated-mannequin test with the standard cited; here they do not.
230 cm (90.6 in) long is unusually generous — most mummy bags on this shelf stop at 210 or 220 cm (86.6 in). 82 cm (32.3 in) at the shoulder tapering to 55 cm (21.7 in) at the foot is a normal mummy profile. If you are tall, this is the one here that fits.
1900 g (67 oz). That is the price of 350 GSM in two layers across a 230 cm (90.6 in) bag, and it is why the packed roll is 24 × 30 cm (9.4 × 11.8 in).
Buy it on the 0 °C (0 °F) comfort figure and the 230 cm (90.6 in) length. Treat the title’s numbers as marketing, because nothing in the listing explains them.
The American Amazon store returned nothing, so the buy link opens a local search rather than a page that is not there.

| Comfort rating | Around 0 °C (0 °F) — stated as the comfort temperature; no standard is named, so it is an unstandardized figure |
|---|---|
| Limit rating | Not stated as a limit — the title carries -23 °C (-9 °F) and -5 °C (23 °F), neither labeled, and no standard is named |
| 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 350 GSM, a fill density in grams per square meter |
| Down or synthetic | Synthetic — stated as polyester, in a double-layer fill |
| Shell denier | Not published on the listing — a soft, breathable, rustle-free outer with a PFC-free water-repellent coating is described, with no yarn weight |
| Baffle construction | Double-layer fill — stated; the baffle pattern itself is not given |
| Packed size | 24 × 30 cm (9.4 × 11.8 in) — stated, in the supplied compression sack |
| Weight | 1900 g (67 oz) — stated, with no label saying what is counted |

| EAN | 4011739601358 |
Two layers of wadding offset against each other, so the stitch lines of one are covered by the body of the other. It removes the cold seams that a single quilted layer leaves, and it is why a 350 GSM bag can be warmer than the figure alone suggests.
Per- and polyfluorinated compounds were the standard chemistry for durable water repellency and are being phased out on environmental grounds. A PFC-free finish beads water less aggressively and is renewed with different products, so it is worth knowing which one you have before washing the bag.
No. Not stated as a limit — the title carries -23 °C (-9 °F) and -5 °C (23 °F), neither labeled, and no standard is named. What the listing does publish instead is the comfort rating: Around 0 °C (0 °F) — stated as the comfort temperature; no standard is named, so it is an unstandardized figure.
7.8/ 10
The one bag here that says the words comfort temperature and gives a single figure. At 1900 g (67 oz) it is a driven-to bag rather than a carried one, and the title numbers should be ignored in favor of the 0 °C (0 °F) the listing actually explains.
Taller sleepers camping in the cold shoulder seasons, where a 230 cm (90.6 in) bag and a stated comfort figure matter more than carried weight.
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.

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.
