I invested in a sleeping bag to bivouac in the mountains in the Pyrenees even in December. I am very satisfied to sleep warm.
I tried it a few days ago in a bivouac at an altitude of 2000 m. After a while I even felt hot. Excellent opening in the feet. Very compact and easy to fold. I'm 1.70cm tall and I fit well in size M, it's not small. Excellent purchase.
Already a user of previous models for several years, quality always there. a bit tight for intensive activity in periods of extreme cold; but suitable in 75% of situations,
Nothing to say about the product, does the job: light, warm. Note: The storage mesh bag was missing on delivery, how do I get one? difficult to find the link on the decathlon website... thank you in advance for your help.
Hello, I was pleasantly surprised by the qualities of this sleeping bag during the first days of use, and new. However, the more I use it, the more it loses its thermal and mechanical qualities. In fact, it (the sleeping bag) loses all its loft, although it is systematically stored in its storage compartment, in a dry place. when I take it out of its storage case, it does not regain any fluffiness, even after several days out of its storage bag, lying flat. Despite this, when I try to use it, its thermal qualities are no longer there. Indeed, while it allowed me to face cold temperatures (from minus 2 to zero degrees Celsius) just in underwear when it was new, I can now barely spend an autumn night at seven degrees Celsius without wool underwear plus a fleece. In other words it does not keep its promises, only after a few uses, despite a lot of attention.
Hello, I have just returned from an expedition to Iceland with nights with negative temperatures but not below -2°/-3° I slept very little because of the cold throughout the stay despite wearing tights and a top in merino (decathlon) A suitable insulating mattress And an MT900 tent We were a team and some had Makalu II (-9) and complained about the effectiveness as well. So I really doubt the temperatures announced I'm leaving again in a month for a another expedition in a cold area and I will therefore be forced to buy a new sleeping bag. Big fan and Decathlon customer for years, I admit to being very disappointed Romain
Excellent down. Easily stored in its compression bag. Warm and light
Good product.
Perfect
feathers were missing in several places, then even -5˚C was extreme...
Does its job perfectly!
good value for money
I only had a chance to use it once, and the temps weren't cold, but the bag felt warm. It is light which is appreciable (even more compact would be the best). I bought a size M, which corresponds to my build. I recommend size L for people who move at night.
Used during the TMB, very cocooning and warm, easy to store in the cover
Very nice and warm sleeping bag. A little smell of duck at first.

Temperature rating
On all our sleeping bags, we display the temperature ratings determined by testing in an independent lab (AITEX) based on European Standard EN 13537 (2016).The ”comfort temperature rating” is the lower limit when a user in the sleeping position is generally in thermal equilibrium and is neither hot or cold (based on a ”standard” woman in normal conditions of use).Choose your sleeping bag based on this feature.
What you must know about temperature ratings
A sleeping bag does not generate heat but ”maintains” heat generated by body. If you are exhausted and cold and you slip into your freezing and damp sleeping bag, you risk staying cold, whatever the sleeping bag's features!These temperature ratings therefore depend on a person's resistance to the cold (build, fatigue, etc.), on their equipment (mattress that insulates from the ground, etc.), on their clothing (naked, underwear, etc.), and on weather conditions (damp, windy, etc.).
Storage instructions
Store your sleeping bag in its storage cover in a dry place because there is the risk of the down deteriorating if it is compressed for too long in its compression sack
