Excellent sleeping bag

My second sleeping bag. Although the bag serves me well, i gave 4 stars because the quality of the zip is mediocre. If they can replace the zip with YKK, that will be awesome. Not something you would like to have when you are camping.

good enough

well it was not 10 outside but it was semi comfortable, we bought the cotton version for better touch which was nice.

Good night

Very well priced. Very comfortable, soft and long enough for a taller than average person. I wish it was maybe 5-10cm wider, but it's a perfect bag. Highly recommended.

Misrepresentation NOT 80cm wide only 72cm!

I wanted a wide sleeping bag as I am quite broad across the shoulders. My old sleeping bag was a bit cosy at 78cm, so an 80cm bag seems good. I travelled about 24 miles to Warrington and bought the bag for £45.00 As soon as I got home I opened the bag and pulled out the sleeping bag, when trying to zip it up I realised it was not the size listed. I got out a tape measure and sure enough it wa much smaller than advertised. It even tells the same lie on the bag that it comes in. The cover/bag is very tight, extremely difficult to put the sleeping bag away. Very poor advertising, in fact it is illegal! I was quickly refunded and had a look at the other sleeping bags on display, the measurements are ambitious on a few. Crazy on this one.

Used products

It is absolutely used by someone.

Good nights sleep

Nice sleeping bag for the money. It’s got plenty of room inside it and doesn’t suffer from fouling up zips like other sleeping bags at this price, which is nice. I’d definitely recommend it to others.

Much better sleeping bags available.

I purchased the sleeping bag after having other Quechua bags which have been great. The temperature at night was well within the limits for this bag but I spent 3 nights shivering! We swapped sleeping bags between each other and the rest of the family found this just as cold as I did, the staff didn't believe anyone could be cold in this bag and repeatedly questioned me when I tried to return it. Really disappointing as we have lots of Quechua products which have been excellent.

Bag Great

The sleeping Bag feels really comfortable, but why oh why do they make the bag it goes in so small had to use my old Outwell covers

Great sleeping bag

Very good quality product. And well made good price

Soft, warm and comfortable

Soft, warm and breathable. Not shiny horrible material like traditional sleeping bags. You can unzip from the top and bottom if you don’t want your feet zipped in. Also like that you can completely unzip and it becomes a duvet.

Cozy Single or Tandem

Very much a holiday bag with its square cut, soft cotton touch. Two can be zipped together offering plenty of room as a double.

Use temperature

We display on all our sleeping bags the comfort temperatures tested by an independent laboratory (AITEX) according to European standard ISO 23537-1 of 21/01/2017. 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 comfort limit temperature?

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).

What you need to know about temperatures

A sleeping bag does not produce heat but retains the heat produced by the body. If you are tired and cold and you slip inside a cold, damp sleeping bag, it is very likely that you will feel cold no matter how good your sleeping bag is! These temperatures therefore depend on the person's resistance to cold (body type, fatigue, etc.), equipment (mattress with insulation, etc.), clothing (naked, underwear, etc.) and weather conditions (humidity, wind, etc.).

Tips before getting into your bag

Dress simply (just 1 layer of clothing is enough). Warm up your extremities: hats, gloves, socks, hand/feet warmers, friction... A flask of hot water can be used as a hot water bottle (if there is no risk of accidental opening!). Contract your muscles (70% of the energy consumed is converted into heat) but without making any movement generating a cold airstream. To wash your sleeping bag less often, we recommend you use a sleeping bag liner.

A score for comparing products' environmental impact

The environmental impact of the product is calculated based on its entire lifecycle and using different indicators. An overall ABCDE score is given to help you easily identify products with the best environmental performance by comparing products of the same type (T-shirts, pants, backpacks, etc.). Decathlon is a voluntary supporter of this environmentally-friendly labeling approach.



Product testing

This sleeping bag is guaranteed for a period of 5 years from the date of sale indicated on the receipt. The product covered by the guarantee will be repaired or exchanged free of charge. The warranty covers product defects excluding any resulting from normal wear and tear and those resulting from abnormal use. The product and sales receipt are required for this special 5-year warranty to be valid.

Storage instructions

Easily store your sleeping bag by stuffing it into its cover feet first. To keep it fluffed up, which will ensure good thermal performance, remove its cover and store it somewhere dry.
