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. 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).
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
The mummy shape optimises thermal insulation (no loss of heat because there is not much air flow or draughts) and saves space, which means that your movements are restricted.

The advantages of a duck down and feather filling
The filling power of down has 3 advantages for mountain sports:
– Thermal insulation thanks to the air trapped in the down and feathers
– Ultra low weight: down is lighter than synthetic wadding while offering the same degree of warmth. This saves even more weight in your backpack
– Ultra-compressible

How to measure the fill power of a down and feather wadding ?
The fill power is a measure of the down’s thermal insulation capacity and its potential to “trap” air. It is expressed in CUIN (cubic inches).
So, down with a higher fill power (higher CUIN number) will occupy more space, trap more air and provide greater thermal insulation.
For this sleeping bag with its 90% down / 10% feathers filling, the fill power is guaranteed to be 800 CUIN or more (international IDFB standard).

What Is RDS Certification?
RDS or “Responsible Down Standard” is a worldwide certification issued by an independent organisation to volunteer brands.
This standard enables us to guarantee the origin of the feathers in accordance with our commitment to use responsible materials. Our suppliers commit to using only feathers from geese and ducks raised for their meat and slaughtered before down and feathers are collected.

Additional sustainable development information
We chose to use a so-called “biton” thread for all the grey-coloured fabrics in this sleeping bag.
Textile dyeing requires a lot of water but also produces waste water from the dye baths. To reduce this impact on the environment, we use only mass pigmentation of one yarn out of every two (Bi-ton), and thus reduce our consumption and our impact on water.

How to maintain a down sleeping bag ?
In short:
1/ machine wash, 30 , with 2 or 3 tennis balls. Gentle spin cycle.
Use special detergent for washing down (ref: 8609821)
2/ tumble dry with 2 or 3 tennis balls, and repeat 2 or 3 times until it is completely dry.

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 and the feathers from escaping.
To do this, we recommend that you use self-adhesive repair patches (ref: 8584596) or ask one of our technicians to do this for you in the workshop of your Decathlon store.
