What is the temperature rating?

We display on all our sleeping bags the comfort temperatures tested by an independent laboratory (AITEX) according to European standard ISO 23537-1 of 21/01/2017. The comfort temperature rating is the lower limit at which the user in relaxed posture is generally in thermal equilibrium and feels neither too cold nor too hot (for a standard woman in normal conditions of use). CHOOSE YOUR SLEEPING BAG ACCORDINGLY

What is the temperature rating (lower limit at which you feel comfortable)?

  • The comfort limit temperature is the temperature limit at which a person curled up in the sleeping bag is in general thermal equilibrium, neither too cold nor too hot (determined for a man in normal conditions of use).We recommend using an insulation mattress to optimise your thermal comfort.

What you need to know about temperatures

A sleeping bag does not produce heat, but retains the heat produced by the body. If you are tired and cold and you slip inside a cold, damp sleeping bag, it is very likely that you will feel cold no matter how good your sleeping bag is! Your thermal comfort will therefore depend not only on climatic conditions (humidity, wind, etc.) but also on your sensitivity to cold (fatigue, etc.), your equipment (insulating mattress, etc.) and your clothing (naked, underwear, etc.)

Tips before getting into your bag

  • Dress simply (1 layer of clothing is enough). Warm-up your extremities: hats, gloves, socks, hand/feet warmers, rubdowns, etc. A flask of hot water can be used as a hot water bottle (as long as there's no chance of it accidentally opening!)
  • Contract your muscles (70% of the energy consumed is converted into heat) but do it without moving as this could create a draught.
  • Use a bag liner to optimise warmth and avoid washing your sleeping bag too frequently.

Style

  • A generous mummy shape that is wide at the shoulders and narrow at the feet to optimise thermal insulation (no heat loss) and make the product more compact, while maintaining some freedom of movement.

Want to know more about the wadding?

  • We use 1 layer of 100% polyester wadding (90% recycled) at 60 gr/m2.
  • It retains its warmth even when wet.

Compatibility

  • Can be twinned with all the Forclaz MT500 sleeping bag models.
  • Can be twinned with the older models in the 2017 "Ultralight" and 2018 "Light" ranges.

ADDITIONAL SUSTAINABLE DEVELOPMENT INFORMATION

  • Textile dyeing requires a lot of water but also produces waste water from the dye baths. To reduce this impact on the environment, for the grey fabrics of the sleeping bags, we dye every other yarn in bulk, thereby reducing our water consumption and pollution.
  • This process can reduce CO2 emissions by 19% compared to traditional dyeing methods.
  • In addition, we use a wadding made from 90% recycled polyester.

How to repair your sleeping bag

  • On a trek, you can snag a sleeping bag, it happens! The good news is that it can be repaired to prevent the tear from getting bigger or the synthetic fibres from escaping.
  • To do this, we recommend that you use self-adhesive repair patches (ref: 8584596).
