Each product sheet specifies the comfort temperature measured in the laboratory, the fill power in cuin, and the weight to enable a choice suited to actual use.\n\u003c\/p\u003e\n\n\u003ch2\u003eChoosing a 3-season sleeping bag based on actual conditions\u003c\/h2\u003e\n\n\u003cp\u003e\n  In France, mountain nights vary significantly depending on altitude, season, and the mountain range. A bivouac in the Pyrenees in June at 1,800 m does not have the same requirements as a night in the Alps in October at 2,500 m. A \u003cstrong\u003e3-season sleeping bag\u003c\/strong\u003e meets this reality with a wide thermal range, but the comfort temperature remains the only reference value for selection. The extreme temperature, often highlighted in marketing materials, corresponds to a theoretical survival threshold rather than a usage metric. The \u003cb\u003eEN 13537 \/ ISO 23537\u003c\/b\u003e standard guarantees temperatures measured in a laboratory using a thermal mannequin, independent of manufacturer claims. It is advisable to allow a margin of 3 to 5 °C compared to the coldest night expected, while taking into account the sleeping pad, humidity, and individual metabolism.\n\u003c\/p\u003e\n\n\u003ch3\u003eDown or synthetic fill for a 3-season bag\u003c\/h3\u003e\n\n\u003cp\u003e\n  The \u003cb\u003edown sleeping bag\u003c\/b\u003e with natural filling (700 to 800 cuin) is preferred for active 3-season use: it offers the best compressibility and the best weight-to-insulation ratio for trekking and \u003cb\u003ebivouacking\u003c\/b\u003e. A \u003cb\u003ewarm down\u003c\/b\u003e bag with 800 cuin fill power and 0 °C comfort compresses into 8 to 12 liters, compared to 16 to 20 liters for an equivalent synthetic one. Synthetic fill, on the other hand, retains some of its insulation in damp conditions, an advantage for spring outings exposed to showers or nocturnal condensation. For a \u003cb\u003ecamping down\u003c\/b\u003e bag transported by car or on routes with little elevation gain, weight becomes secondary and comfort in terms of volume may take priority.

A model with 0 °C comfort is suitable for high-altitude bivouacs from spring to autumn, cool summer nights in the high mountains, and long-distance itineraries such as the GR20 or the Tour du Mont-Blanc. A model with +5 °C or +10 °C comfort is better suited for summer \u003cb\u003ecamping down\u003c\/b\u003e in the lowlands or for mild nights without significant temperature swings.

A \u003cb\u003ewarm down\u003c\/b\u003e model with 800 cuin fill power and 0 °C comfort weighs between 500 g and 900 g depending on its construction, compared to 1.2 to 1.5 kg for an equivalent synthetic one. On a 7 to 10-day trek, this difference of 400 to 600 g is noticeable. Models with light synthetic fill remain relevant for static camping or outings where weight is less of a constraint.

This is a practical advantage for trekking: tent condensation, morning dew, and ambient humidity at altitude.

Note on the weight\/insulation ratio: for an equivalent temperature range, 700-800 fill power down insulation would weigh less than 500 g — synthetic is a compromise here in favor of moisture tolerance and simplified maintenance, at the expense of weight.
