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.
The bottom line 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.
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.
40 °F to 77 °F is roughly 4 °C to 25 °C, and 62 °F to 75 °F is roughly 17 °C to 24 °C. 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.
Selling between 31 € and 32 € across the German, French and Spanish Amazon stores when this page was checked.
It also sells on the British Amazon store in the local currency, which the range above does not cover — that range counts euro stores and nothing else.
The Italian Amazon price sits more than 1.6× above the cheapest store. That gap usually means a reshipper rather than a local seller, so that listing is kept out of the range above.
Catalogued on the American Amazon store with nobody selling it: the reference is there, the offer is not.

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.
Mummy · 400 GSM synthetic · comfort +4 °C and limit -2 °C stated · 1.55 kg total · compression sack · no standard named
