The comfort rating, not the season name, describes your night · review
A half-rectangular bag whose only figures are two Fahrenheit ranges, with no weight, no packed size, no fill and no fabric published anywhere.
A half-rectangular shape, a nominal temperature range of 40 °F to 77 °F with an optimal comfort range of 62 °F to 75 °F, double-sided zips along the sides, a separate zip at the bottom to regulate foot temperature, full opening into a quilt or cushion, a waterproof outer protective shell, a skin-friendly lining, and washing at 30 to 40 °C (86 to 104 °F).
40 °F to 77 °F is roughly 4 °C (39 °F) to 25 °C (77 °F), and 62 °F to 75 °F is roughly 17 °C (63 °F) to 24 °C (75 °F). Those conversions are ours; the maker publishes Fahrenheit only.
Read the second range rather than the first. The nominal range describes the seasons the maker has in mind; the optimal comfort range is where the bag is said to work, and it is a summer figure. No standard is named for either, so neither is a laboratory value under EN 13537 or ISO 23537.
The fill. Nothing at all: no material, no density, no weight. That is unusual even on this shelf, where a GSM figure is normally the one insulation number given.
The fabric. A waterproof shell is claimed and never named.
Weight and packed size. Both absent, on a bag whose title sells hiking and backpacking.
The zip arrangement. Two side zips and a foot zip means you can vent the feet, open one side, or lay the whole thing flat. That is a real design decision, and it is described clearly.
Take the optimal range at face value and treat this as a summer bag. If you need to know what it weighs, ask before buying.
The American Amazon catalog lists it with no seller standing behind the entry.

Because the listing sells into a market that reads Celsius, and 40 °F looks colder than it is. The conversions here are ours and are marked as such; the published figures remain 40 °F to 77 °F nominal and 62 °F to 75 °F optimal.
Yes — feet are where most people overheat first, and a separate zip at the bottom lets them vent without opening the whole bag and losing the warmth around your shoulders. It is a genuinely practical feature on a summer bag.
No. Not stated as a limit — the maker publishes a nominal range of 40 °F to 77 °F, about 4 °C (39 °F) to 25 °C (77 °F) converted here, without calling either end a limit. What the listing does publish instead is the comfort rating: Given as an optimal comfort range of 62 °F to 75 °F, which is about 17 °C (63 °F) to 24 °C (75 °F) converted here — an unstandardized figure.
7.8/ 10
A summer bag with a well-thought-out zip arrangement and almost no specification. If the temperature suits the nights you camp in it will work; there is nothing published to weigh it, pack it or compare it.
Warm-weather use where the foot vent and the full opening matter, and where nothing has to be carried far.
Amazon reports what buyers took in the month before this page was last checked: at least 200.
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.
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.
Mummy · 300 GSM cotton and hollow-fiber fill · comfort 15 °C (59 °F) to 20 °C (68 °F) · about 1300 g (45.9 oz) · 35 × 25 cm (13.8 × 9.8 in) packed
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
