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
Mummy shape that is wide at the shoulders and more narrow at the feet to optimise thermal insulation (no heat loss) and compactness, while maintaining relative freedom of movement.
Width at the shoulders 74 cm, height at the feet 36 cm in size L. 78/38 in XL, 70/34 in M

Want to know more about the wadding?
We use 3 layer of 100% polyester wadding (70% recycled) of 115 g/sqm.
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.
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 CO02 emissions by 7% compared to traditional dyeing methods.
In addition, we use a wadding made from 70% 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).
If you don’t feel comfortable doing this yourself then a heat-bonded patching service is available at the workshop of your Decathlon store.

MaterialRecycled polyester
Textile part made of 1% recycled polyester
We have incorporated recycled polyester into this product (instead of conventional polyester, which is itself derived from petrochemical plastic). What does this mean? In addition to being technical, this product has been designed taking into account its environmental impact: using recycled polyester means recovering and transforming products destined to be thrown away, such as production offcuts or plastic bottles, instead of using new oil resources.

ProcessBiton
1% of the fabric color is made by dyeing only one yarn out of two
Dyeing textiles requires the use of lots of water, whilst also generating water waste from dyeing vats. To reduce this environmental impact, we use just one dyed mass-coloured thread out of two out, subsequently reducing our consumption of water and our impact on it.
