How can I keep warm in the MT500 5°C sleeping bag?

Dress simply (1 layer of clothing, ideally made from merino wool, is enough).
Protect your extremities with a hat, gloves, socks and hand warmers if needed.
Use a sleeping bag liner to optimise heat and avoid over-washing your sleeping bag Choose a mattress with good insulation (R-value> 3).
And an extra tip: contract your muscles (70% of the energy consumed is converted into heat) but do it without moving as this could create a draught!

How to repair your MT500 5°C sleeping bag

On a trek, you can snag a sleeping bag, it happens! The good news is that it can be repaired to prevent the tear from getting bigger or the synthetic fibres from escaping.
To do this, we recommend that you use self-adhesive repair patches (ref: 8584596).

If you don’t feel comfortable doing this yourself then a heat-bonded patching service is available at the workshop of your Decathlon store.

Do you want to know more about the wadding used in your MT500 5°C sleeping bag?

We use 3 overlapping layers of 60 g/m2, 100% polyester wadding for the top and bottom of the sleeping bag.

The wadding is made from silicone-coated spiral fibres that make it highly compressible and highly robust.
Despite its low thickness, it has high insulation properties thanks to the air trapped inside, and remains lightweight.

It retains its warmth even when wet.

How robust is fabric of the MT500 5°C sleeping bag?

On the outside, it is made of 100% polyamide, 38 g/m², 20 denier. This fabric can withstand up to 20,000 abrasion cycles.

Robustness is calculated using the Martindale test (Standard 12 947-2). This test involves rubbing the bag material against another material to assess the product's abrasion resistance.

The inner lining is made from a 100% polyamide fabric in 20 denier, weighing 35 g/m2.

What is the comfort 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 lower temperature limit?

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).

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.
