Technical Information

1
Temperature of use:
All our sleeping bags display the temperature ratings, tested by an independent laboratory (AITEX), in accordance with the European standard NF ISO 23537 - 2017. The "comfort temperature" is the lower comfort limit at which a user in relaxed position is in overall thermal balance and is neither hot nor cold (determined for an average woman in normal conditions of use). Choose your sleeping bag according to this criterion.
2
What are the limit temperatures for usage?
Limit temperature: temperature limit at which the user of the sleeping bag in huddled-up position is generally in thermal equilibrium and is neither cold nor hot (determined for a standard man under normal conditions of use).We recommend using an insulation mattress to optimise your thermal comfort. This sleeping bag is filled with feathers and down. The thermal insulation may drop in damp conditions.
3
However, this is 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! These temperatures therefore depend on the person's resistance to cold (bulk, fatigue, etc.), equipment (mattress with insulation, etc.), clothing (naked, underwear, etc.) and weather conditions (humidity, wind, etc.).
4
For greater comfort, before getting into your sleeping bag:
Dress simply (1 layer of clothing is enough). Warm-up your extremities: use hats, gloves, socks, bed warmers, rubbing, etc. A flask filled with hot water can be used as a foot or bed warmer (so long as there's no chance of it opening by accident!) Contract your muscles (70% of the energy consumed is converted into heat) but without making any movement generating a cold airstream. Use a silk or thermal sleeping bag liner to maximise warmth & hygiene inside your bag.
5
Shape:
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. Width at the shoulders 72 cm, height at the feet 26 cm in size L. Ergonomic hood with drawcord. Double slider, lined with an anti-cold duvet flap, side opening. H-shaped compartment structure to reduce thermal bridges.

Size and thermal insulation:
Try your sleeping bag before buying it to choose the right size for your comfort.Ideally, you should not be pressed up against the fabric, at the feet or head, and the fabric should not be taut. This would create thermal bridges that lower the insulation of your sleeping bag. Conversely, a sleeping bag that is too big will be harder to heat up and will not be as good at insulating the heat generated by the body.
8
Size and thermal insulation (continued):
The weight, volumes & sizes may vary slightly owing to production tolerances. Volume & dimensions in the bag may vary according to the compression applied to the product.
9
Origin of feathers and RDS certification:
Thanks to our traceability system, we can guarantee the origin of the feathers in accordance with our commitment to use responsible materials. Our suppliers are committed to using only feathers that come from ducks (Chinese origin) that are bred for their meat and which are plucked after slaughtering. We have been awarded RDS certification (Responsible Down Standard) by a third-party organisation. http://developpement-durable.decathlon.com/documents-et-rapports/documents/

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
11
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. 90% duck down, 10% duck feathers. Filling Power of the down: 800 CUIN (IDFB standard) The feather filling requires special care. Follow care advice.

Care instructions
Machine wash on a delicate cycle at 30°C, wash inside out, with 3 or 4 washing balls (or clean used tennis balls). Use a detergent for feathers and down. Rinse multiple times. Spin dry on a slow and gentle cycle. Required step: Tumble dry on low heat on a delicate cycle. Finish off drying outside, ideally in the sun, on both sides to prevent the down from forming clumps. Dry thoroughly before storing.

Eco-design
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 chose to use a dyeing process called "bi-ton" which involves dyeing one in every two yarns. This dyed yarn is also made from a bulk dyeing process which incorporates the colour pigments from the yarn manufacturing phase onwards.
