Product Customer Reviews
Excellent value for money, satisfied. I would have preferred the zip on both sides to be able to take my arms out at higher temperatures
Great product
Perfect
And the 3rd purchase for my daughter used for treks, very useful, saving space in the bag, not to be spared. I recommend
Excellent product. Lightweight and very compact when stored compared to other sleeping bags
Slept nice and warm. Super quality, especially for this price
I bought this duvet at the end of August 2024 and I made my first bivouac in the Pyrenees in September 2024 and after my first night with this duvet, feathers came out even though I took great care of this duvet, so I looked more closely and discovered that the seam had come loose in one place, I still spent my second night of bivouac there by putting adhesive tape so that the feathers no longer come out but it is very dangerous to sleep in a defective duvet knowing that the nights start to be very cool in September.. very disappointed when this one still costs €200! The price seems very high to me compared to the quality..
A nice sleeping bag, used for 3 seasons. In spring and autumn together with thermal clothing and an inflatable mat - I have never been cold. In summer, when the temperature at night is about 15 degrees, I do not zip myself in it, but sleep as if under a blanket - thermal comfort is acceptable, there is no feeling of heat.
Excellent option for those who want a lightweight sleeping bag with great heating power. Ideal for hikers
Compact duvet, easily transportable and keeps you warm. Sarcophagus shape so narrow at the legs but conforms to the description. I am satisfied with my purchase.
Not yet tested in the field but intended for bivouacs in the forest, the product seems promising: - Soft and quiet fabrics. - Water repellency of the fabric a real plus to cope with the morning dew. - A minimum weight and bulk for the thermal capacities presented. The swelling did not seem very important to me that said. I hope that the duration of storage in the store in the compression bag has not altered the product knowing that it is recommended to keep it in its storage bag. Transfer that I hastened to do. Hoping not to end up as an ice cube at the next bivouac.
Warm, comfortable, does not take up space when compressed. Ideal for hiking routes.
in other sleeping bags the comfort temperature works for me with practice. Here it doesn't. In my opinion the comfort of this sleeping bag is +4 degrees, not 0
Meets expectations and was a perfect companion on the GR20. Warm, breathable, compact on the bag, easy to store.
Perfect duvet for treks in slightly cooler seasons or in the mountains. Light and compact. Best value for money. I tested it during nights around 0•C: RAS! The investment is worth it

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 don't make any movements that cause cold draughts.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.Width at the shoulders 28.3 Inch (72 cm), height at the feet 10.2 Inch (26 cm) in size L.

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 fts thermal insulation capacity and its potential to Inchtrap Inch 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).
Storage instructions
To maintain its fill power, which is necessary for its insulation properties, store your sleeping bag by stuffing it in the mesh bag provided, feet first. Can be stored flat.
