The comfort temperature, measured according to the EN 13537 or ISO 23537 standard, assumes the use of an insulating mattress (R-value ≥ 3), long thermal underwear, and a closed hood in a dry environment. In real-world conditions—altitude, humidity, wind, fatigue—it is recommended to allow a margin of 3 to 5°C compared to the coldest expected night.\u003c\/p\u003e\n\n  \u003ch3\u003eInsulation: down or synthetic?\u003c\/h3\u003e\n\n  \u003cp\u003e\u003cb\u003eDown insulation\u003c\/b\u003e offers the best weight-to-insulation ratio for trekking and bivouacking in dry conditions.
