This geometry reduces the volume of air to be heated around the torso while leaving room to bend the legs while sleeping. The comfort temperature is -1.7°C — a value measured in the laboratory according to the ISO 23537 standard, using an insulating mat, long underwear, and the hood closed.

The \u003cb\u003e20D ripstop\u003c\/b\u003e fabric with DWR water-repellent treatment offers resistance to light dew, but provides no protection in the event of sustained rain.
