What is the temperature rating?
All our sleeping bags display the comfort temperatures tested by an independent laboratory, according to European standard ISO 23537-1. The comfort temperature is the lower limit at which the user is in general thermal equilibrium, feeling neither too cold nor too hot (for an average person in normal conditions of use). Use this rating to choose the sleeping bag that’s right for you.
What is the temperature rating (lower limit at which you feel comfortable)?
The comfort limit temperature is the lower limit at which the user is in general thermal equilibrium, neither too cold nor too hot (for an average person in normal conditions of use).We recommend using an insulating mattress to optimize your thermal comfort.
What you need to know about temperature
A sleeping bag does not produce heat but rather retains the heat produced by the body. If you’re chilled when you slip into a cold, damp sleeping bag, it’s very likely that you’ll 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 (pyjamas, underwear, etc.).
Some advice to consider before you get into your bag
Dress simply (one layer of clothing is enough). Warm up your extremities: hats, gloves, socks, hand/feet warmers, rubdowns, etc. A container 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 draft.
Use a bag liner to optimize warmth and avoid washing your sleeping bag too frequently.

The advantages of duck down and feather filling
The fill power of down has three advantages for hiking:
- The air trapped in the down and feathers provides thermal insulation.
- 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.
Measuring the fill power of down and feather wadding
Fill power is a measure of the down’s thermal insulation capacity and potential to trap air. It is expressed in cuin (cubic inches).
Down with higher fill power will take up more space, trap more air, and provide greater thermal insulation.
This 90% down, 10% feather sleeping bag has a guaranteed fill power of at least 800 cuin (European standard).
What is RDS certification?
The Responsible Down Standard, or RDS, is a worldwide certification issued by an independent organization to volunteer brands.
Our traceability system guarantees the origin of the feathers in accordance with our commitment to use responsible materials. Our suppliers commit to only using feathers from ducks raised for their meat and slaughtered before down and feathers are collected.

More sustainable development information
Bi-ton thread was used for all the grey-coloured fabrics in this sleeping bag.
Textile dyeing takes a lot of water and dye baths produce wastewater. To reduce the environmental impact, we use dope dying on one yarn out of two (bi-ton).
How to maintain your down sleeping bag
Even if you regularly use a bag liner, you will need to wash your down bag from time to time. How to care for your sleeping bag:
In short:
1/ Machine wash at 30°C with two or three tennis balls. Use a gentle spin cycle.
Use special detergent for washing down (ref: 8609821).
2/ Tumble dry with two or three tennis balls and repeat two or three times until completely dry.
How to repair your sleeping bag
While hiking, you might snag your sleeping bag. 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 using self-adhesive repair patches (ref: 8584596).
