DOWN

The Svalbard 510 down sleeping bag is made with European duck fill. The down to feather content is 92/8, and the springiness is 800 cuin. We also have to boast – we fill our sleeping bags in Poland!

Footbox in the form of a shark fin – The bottom of the sleeping bag sewn at an angle of 70 ° improving the comfort of use, especially for people on the upper limit of the size of the sleeping bag. Such a design is tailored to the anatomical positioning of the feet while sleeping, which also contributes to improving the thermal performance of the sleeping bag.

Description

The thermal performance of this sleeping bag has been estabilished based on tests of 9 different models of Fjord Nansen sleeping bags in the laboratory. Therefore, you can rely on our recommended temperatures. You can read more about it in the article TEMPERATURE TESTING OF SLEEPING BAGS – KEY TO GOOD SLEEPING.

 

Temperature range:

Note: in the name we specify T lim – this is the lowest temperature at which a “standard man” can sleep comfortably. Women or people who freeze easily, should be guided by the thermal parameter T comfort when choosing a sleeping bag.

 

Temperature Ranges according to EN 23537 – these refer to a standard man and a standard woman after average exertion.

NOTE: Sometimes the sensation of cold can be different in different people. Factors such as fatigue, hunger, malaise, previous hypothermia, age, metabolism, body fat thickness, etc. also affect the way the cold feels.

 

  • Upper comfort limit (T max) – the temperature at which a “standard man” does not sweat, and excessive temperature does not interfere with his sleep.
  • Comfort (T comf) – the temperature at which a person is in thermal equilibrium and does not feel cold. This value refers to a “standard”, full woman, after an average effort. This parameter should guide women when choosing a sleeping bag.
  • Limit temperature (T lim) – the lowest temperature at which a “standard man” can sleep comfortably. This parameter should be followed by men when choosing a sleeping bag.
  • Extreme temperature (T min) – exceeding this value causes the risk of hypothermia and means conditions in which you can survive for six hours at most (a parameter based on the feelings of the “average woman”). We should not be guided by this temperature when buying a sleeping bag.
