Ergonomic hood with drawcord.
Double collar to prevent heat from escaping.
Anti-cold flap along the zip to prevent heat loss.
Double zip for optimum ventilation.
Inside pocket.
How do you keep warm in the MT500 -5°C sleeping bag?
Dress simply (1 layer of clothing, ideally merino wool, is enough).
Protect your extremities with a hat, gloves, socks and warmers if necessary.
Use a sleeping bag sheet to optimize warmth and avoid over-washing your sleeping bag. Choose a mattress with good insulation (R-value > 3).
And a little tip: contract your muscles (70% of the energy consumed is transformed into heat), but without making any movement that generates cold draughts!
How to repair your MT500 -5°C sleeping bag?
On a trek, a tear in your sleeping bag can happen! The good news is that it can be repaired to prevent the tear from getting bigger or the synthetic fibers from escaping.
We recommend the use of self-adhesive repair patches (ref: 8584596).
And if you don't feel comfortable performing this operation, an iron-on patch installation service is available in your Decathlon store.
Would you like to know more about the wadding used in your MT500 -5°C sleeping bag?
We use 3 layers of wadding on top of each other:
- two of 115 gr/m2, 100% polyester.
- and one of 150 gr/m2, 100% polyester.
Wadding is composed of siliconized helical fibers, giving it high compressibility and resilience.
Despite its thinness, it has a high level of insulation thanks to the air trapped inside, while retaining a low weight.
It has the advantage of retaining its warmth even when wet.
How strong is the MT500 -5°C sleeping bag fabric?
On the outside, the fabric is 100% polyamide, 38 g/m², 20 denier. This fabric withstands 20,000 abrasion cycles.
Resistance is calculated using the martindale test (Standard 12 947-2). This test consists of rubbing the bag material against another material to determine the wear limits of the product.
Inside, the lining uses a 100% polyamide 35 g/m2, 20 denier fabric.
What is comfort temperature?
All our sleeping bags feature comfort temperatures tested by an independent laboratory (AITEX) in accordance with European standard ISO 23537-1:2022.
Comfort temperature is the lower limit of comfort at which a person in a relaxed posture is in overall thermal equilibrium and neither cold nor hot (determined for a standard woman and under normal conditions of use).
Choose your sleeping bag according to this temperature.
And what is the comfort limit temperature?
The comfort temperature limit is the temperature at which a person curled up in a sleeping bag is in overall thermal equilibrium and neither cold nor hot (determined for a man and under normal conditions of use).
An important clarification concerning ISO 23537-1
For the purposes of this standard, the protocol for measuring the thermal performance of a sleeping bag uses a mattress whose thermal resistance corresponds to an R-value of 4.8.
This means that if you use a less insulating mattress, the thermal performance of your sleeping bag will be lower.
We therefore advise you to use an insulating mattress to optimize your thermal comfort.
