Check the temperature ahead

I bought this sleeping bag for my university camping, the weather was 10-11 degrees, but still, I had to double my sleeping clothes at night, because of the cold. It might be me, who is always cold, but still, take notice of temperatures ahead. What I love is that sleeping bag becomes so small, it barely takes any place in my 55 litre backpack. Quite a lot of times I spilled water on my sleeping bag, but it didn’t get wet and I love the hood of it, so you can use the elastic to adjust the size of the hood to be warmer. The zipper is ok, it is both sided, but still tangling in the bag itself. The zipper has two zips, so you can unzip from bottom, or the top.

Very practical

The two zip feature works well for when it gets too hot. Also seems slightly wider at the feet which allows for more manoeuvrability

Very light and compact

I bought this for my PhD to take on a school journey. It is very compact and takes little space when packing I to suitcase. Bits also easy to get back into it's bag.

Extra roomy but still lightweight

I liked the extra width and length and the fact that it still meets my weight criteria for backpacking.

Excellent bag at a great price, would have been perfect if it was in camo.

Perfect size

It’s great For warmer weather and is so small!

Small to carry, more room for other camping gears

The sleep bag can squeeze into small bag. It is useful

Review for sleeping bag 15 degree

Good quality.

Lightweight and compact.

I doubt you’ll ever get a better compact sleeping bag than this one. It’s comfortable and compact. Does okay till 10-12 C’. The stitches seems pretty durable and so does the material. However, it doesn’t gives much cushioning. You’ll need the either use a plain surface or a mat under it.

Feel cold even at 18 degree Celsius, leave apart 15 - 10 Celsius temperature as mentioned by Decathlon. Quality of products is decreasing day by day at decathlon, Senior officials must step in to save reputation. Note - I know how to do layering and which sleeping mat, tent i should use. [everything was purchase from decathlon, so don't embrace yourself by telling me to use good mat or tent.

Hello Pradeep

Thank you for your valuable review. We are sorry that you were not satisfied with the product.

Since you were not satisfied with the product, Please feel free to kindly visit your nearest Decathlon store and get the product exchanged/refunded. Our team at stores will be more than happy to assist you for the same.

I hope the information was helpful. Kindly write back me in case of any further queries.

User temperature

On all of our sleeping bags, we display the comfort temperatures tested by an independent laboratory (AITEX) according to European standard NF ISO 23537 - 2017.The temperature rating is the lower limit at which the user is generally in thermal equilibrium and feels neither too cold nor too hot in a relaxed pose (for a standard woman and in normal conditions of use). Choose your sleeping bag according to the latter.

What are the limit temperature of use?

Limit temperature:temperature at which the user huddled up in the sleeping bag is generally in thermal equilibrium and feels neither too cold nor too hot (defined for a standard man under normal conditions of use).

However, what you need to know about temperatures

A sleeping bag does not generate warmth but retains the warmth produced by the body. If you feel tired and cold and slip into a cold and damp sleeping bag, you are likely to feel cold, however good it is! These temperatures therefore depend on the person's resistance to the cold (bulk, fatigue, etc.), their equipment (mattress that insulates from the cold, etc.), their clothing (naked, underwear, etc.) and the weather conditions (humidity, wind, etc.).

For greater comfort before sliding into your sleeping bag

Dress simply (just one layer of clothing is enough). Keep your head, hands and feet warm: hats, gloves, socks, hand or feet warmers, rubdown, etc. A bottle full of hot water can be used as a hot water bottle (as long as it will not open accidentally!) Contract your muscles (70% of the energy consumed is transformed into heat). However you should do this without moving as this can cause draughts of cold air. Use a liner sheet, ideally made of silk, to optimise the warmth inside your sleeping bag.


"Generous" mummy shape: wide at the shoulders and more narrow at the feet to optimise thermal insulation (no heat loss) and compact size, while retaining some freedom of movement.Width at shoulder height 76.5 cm and at feet height 32 cm in size L.Ergonomic hood with drawcord.Two side zips with double sliders, lined with a flap (sausage-shaped) made of insulating wadding (thermal bridges) and side openings.
