From the user’s perspective, it is necessary to focus on the validation of sleeping bag properties. The user should determine the conditions in which the sleeping bag will be used, because a universal sleeping bag doesn’t exist to all conditions. The main information for choosing a sleeping bag is a graph according to EN 13537.

Charakteristika spacích pytlů

It is important to choose a sleeping bag with the temperature comfort close to the most common use to which it will put. The farther from the temperature, the bigger risk of hypothermia.

Properties of the finished product:

  • Thermal properties
    Using manikin the temperature of thermal comfort Tcomf is determined (it's the temperature when in a relaxed body position the user doesn't feel cold),
    Tlim means the limit value (this is the temperature when in the huddled body position the user doesn't feel cold),
    Text is the extreme temperature (hypothermia health danger).
  • Transmittance of heat and vapours
    the ability to remove water vapour through the bag surface
  • Bag dimensions
    verification of internal dimensions with respect to the height of the body
  • The volume of the compression bag
    compressibility with respect to ease of packing into a bag
  • Weight

Filling properties

  • Feather: the composition, hygienic properties, penetration, density are tested
  • Other materials: mass per unit area

Mechanical properties

  • Abrasion resistance
  • Tear resistance
  • Determination of pilling
  • Test of zippers - number of opening and closing cycles

Colour fastness

  • Colour fastness to washing
  • Colour fastness to artificial light
  • Colour fastness to perspiration
  • Colour fastness to rubbing

Health – hygienic properties

  • Testing of selected indicators of health - hygienic properties (formaldehyde, pH, heavy metals, aromatic amines)
  • Antimicrobial properties
