The comfort rating, not the season name, describes your night · review
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.
A mummy cut at 210 × 75 cm (82.7 × 29.5 in), a 300 GSM fill of cotton and hollow fiber, a comfort range of 15 °C (59 °F) to 20 °C (68 °F) with a note that the bag is also usable at 0 °C (0 °F), a weight of about 1300 g (45.9 oz), a packed size of about 35 × 25 cm (13.8 × 9.8 in) reached with compression straps, a water-repellent hard-wearing outer, and two-way zips that open from top and bottom.
15 °C to 20 °C is the comfort band the maker publishes. 0 °C appears in the same bullet as a further claim of usability.
Those two are fifteen degrees apart and no standard sits behind either. Under EN 13537 or ISO 23537 the comfort figure would be a single temperature from a heated-mannequin test — an indication, not a promise. Here it is a description, and the 0 °C (0 °F) is a remark alongside it.
Cotton and hollow fiber. Naming both is unusual and useful. Cotton is pleasant against the skin and heavy; it also holds moisture and gives it up slowly. Hollow fiber is the synthetic that does the lofting.
About 1300 g (45.9 oz), into about 35 × 25 cm (13.8 × 9.8 in) with the straps pulled. Both published, both in the same bullet, which makes the carrying decision straightforward for once.
210 × 75 cm (82.7 × 29.5 in) is a compact mummy. If you are over about 185 cm (72.8 in) tall, check the length against your own before the hood becomes the reason it does not work.
The American Amazon store returned nothing, so the buy link opens a local search rather than a page that is not there.

Cotton is comfortable against the skin and takes on moisture readily, and it is slow to give it back. In a bag used on damp nights that means more weight carried and a longer dry-out. The listing names it plainly, which is more than most do.
As a separate sentence from the comfort range, and not as a tested figure. The maker publishes 15 °C (59 °F) to 20 °C (68 °F) as the comfort band and adds that the bag is usable at 0 °C (0 °F). No standard is named for either, so the fifteen-degree gap between them has nothing published to explain it.
No. Not stated as a limit — the maker adds that the bag is also usable at 0 °C (0 °F), which is not published as a limit figure and names no standard. What the listing does publish instead is the comfort rating: Given as a range of 15 °C (59 °F) to 20 °C (68 °F) — an unstandardized figure.
7.8/ 10
A well-measured summer and shoulder-season bag: weight, pack size and fill materials all on the page. The temperature claims are the weak part, and the 0 °C (0 °F) line should be read as a remark rather than a rating.
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.
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.
