Product Customer Reviews
excellent value for money, a bit bulky but I don't have too many references in mind to be able to really judge
Nothing more to say, it is perfect (as long as you stay within the comfortable temperature)
GOOD.
Especially the ease of carrying encourages one to buy the product and the Decathlon warranty makes the product worth buying.
Good thermal insulation effect
Still a little expensive for a duvet but otherwise super practical. It doesn't take up too much space, this one is also very warm.
Not good as compared to price
Too costly
We all have one in the family! Ideal! It is perfect for the most classic temperatures
Excellent product
I recommend
Good product
Comfortable, warm and very practical.
Good lightweight sleeping bag for summer and a really good price. I'm 5'8" and got the regular size and it os the perfect length & quite wide for this type of bag. My tip is to not use the compression bag it comes with as you can stuff it in the bottom of your pack and it takes no room up and pack the rest of your kit on top of it as it compresses it down better. ots my go to summer bag now.
A light travel sleeping bag for cycling, for example, does not take up much space and fulfills its purpose. Usable from spring to autumn, when temperatures do not drop much below 10°.

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 do it without moving as this could create a draught. Use a bag liner to optimise warmth and avoid washing your sleeping bag too frequently.
