The comfort temperature is +5°C, measured according to the GB\/T 38426-2019 and ISO 23537 standards using a thermal mannequin, insulating mat, and long underwear. In field conditions without this equipment, allow for a margin of 3 to 5°C. The mummy cut includes an opening at the feet, allowing you to walk around without leaving the bag — useful when preparing for the day at a bivouac. The YKK zipper can be accessed from the inside.\u003c\/p\u003e\n\u003ch3\u003eSUNDOUCE Gold synthetic filling: advantages in humid conditions\u003c\/h3\u003e\n\u003cp\u003eThe \u003cb\u003eSUNDOUCE Gold 60 g\/m² double-layer\u003c\/b\u003e filling consists of synthetic microfilaments that retain their insulation when they absorb moisture — unlike natural down, which loses a significant portion of its effectiveness when wet. This is a practical advantage for trekking: tent condensation, morning dew, and ambient humidity at altitude. The stated insulation power is 5.29 CLO with an antibacterial inhibition rate greater than 90% maintained after machine washing. The outer \u003cb\u003eGRS-certified 20D nylon\u003c\/b\u003e fabric features a fluorine-free water-repellent treatment. 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.
