TECHNICAL INFORMATIONS

What is the temperature rating?

All our sleeping bags display the temperature ratings, tested by an independent laboratory (AITEX), in accordance with the European standard NF ISO 23537 - 1:2022. 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 according to this criterion.

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.

An important clarification concerning the ISO 23537-1 standard

In the context of this standard, the measurement protocol of a sleeping bag’s thermal protection uses a mattress with thermal resistance equal to an R-value of 4.8.

This means that by using a less insulating mattress, the thermal performance of your sleeping bag will be lower.

We therefore recommend you use an insulating mattress to optimise your thermal comfort.

Some advice to consider before you get 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 2 layers of overlapping wadding:
- One of 115 g/sqm, 100% polyester,
- and one of 150 g/sqm, 100% polyester.
The wadding is made from silicone-coated spiral fibres that make it highly compressible and highly durable.
Despite its low thickness, it has high insulation properties thanks to the air trapped inside, and remains lightweight.
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.

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).

If you don’t feel comfortable doing this yourself then a heat-bonded patching service is available at the workshop of your Decathlon store.
