Much too thin, even for 10 degrees

I bought the sleeping bag because I was looking for a warm one that was small in size. Unfortunately, I didn't sleep a wink and froze all night. It's much too thin and not suitable at all, even though it was 10 degrees. If it had been 0 degrees, I would probably have frozen to death.

The best choice at this price

I have used the sleeping bag many times, both in the lowlands at a temperature of approx. 5-10°, and above 2000 m above sea level at a temperature of approx. 0°, and it worked well. Despite the often high humidity, it did not absorb moisture. A very big plus is the wide size range, which, considering my short height, allowed me to maintain better comfort and significantly reduce weight. After checking it out for myself, this time I bought another one for my husband. I recommend it with a clear conscience.

Compact, warm, beautiful design. But too expensive! Don't hesitate to take a size larger for more comfort/room.

Good, but the problem comes out in the wash

A rather good sleeping bag for the price. After several uses, I washed it for the first time today and despite washing and drying according to the instructions, a lot of down moved between the chambers and some were almost empty. Fortunately, it is possible to move the fluff back somehow and after 2 hours of play I achieved even distribution.

Very good product, tested in Norway at temperatures close to 0, under a tent. Comfortable, and incredibly easy to store.

Better than other specialist brands, keeps you warm and very light

after 1 wash and dry, no down on a number of strips

Warm sleeping bag. Unfortunately, after washing and drying once (the way I have been washing/drying my down sleeping bags for years without any problems), the down has completely disappeared in a number of strips. There is no way to get the filling back there. Sleeping bag no longer usable after 1 trip of 4 days. Worthless product.

The sleeping bag is good for the price, but it certainly does not have a comfortable temperature of up to 0°C, already at temperatures around 3°C you can feel the cold in it. The sleeping bag also looks like it has been stretched out after a few sleeps.

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.


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.
