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 warm and comfortable

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.

Good price

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. In Decathlon we claim the temperature rating on the basis of in-use product tests we do with different individuals. Since the feeling of cold is subjective from person to person we cannot put a bench mark on this topic.

However we want our users to be satisfied and have happy memories from their camping adventures with our products, feedback like these helps us to improve and upgrade our products continuously.

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.

Temperature rating:

We display the comfort temperature ratings on all our sleeping bags. These are tested by an independent laboratory (AITEX) in compliance with European standard EN 13537 of 11/04/2002. The comfort temperature rating is the lowest temperature at which a user in a relaxed position is in thermal equilibrium and feels neither hot nor cold (determined for an average woman in normal conditions of use). Choose your sleeping bag accordingly.

What are the temperature ratings?

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

However, this is what you need to know about the temperature ratings:

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 (bulk, fatigue, etc.), equipment (mattress with insulation, etc.), clothing (naked, underwear, etc.) and weather conditions (humidity, wind, etc.).

For greater comfort, before getting into your sleeping bag:

Do not overdress (1 layer of clothing is enough). Warm up your hands and feet: use hats, gloves, socks, bed warmers, rubbing, etc. A flask filled with hot water can be used as a hot water bottle (so long as there's no chance of it opening by accident!) Contract your muscles (70% of the energy consumed is converted into heat) without moving as this could cause a draught of cool air. Use a sleeping bag liner. Ideally, this should be made of silk to maximise the warmth inside your sleeping bag.
