Features of the MT 500 5°C Sleeping Bag

We display the comfort temperatures that are determined by an independent lab (AITEX) on all our sleeping bags, in accordance with the international standard ISO 23537-1: 2022. 
Comfort temperature is the minimum temperature at which an average person (female, 25 years old, 60 kg [132 lb], 1.60 m [5’3”]) feels comfortable and not cold when they are in a relaxed position.

Choose your sleeping bag accordingly.

What is comfort temperature?

The limit temperature rating is the minimum temperature at which an average person (male, 25 years old, 70 kg [154], 1.73 m [5’8”]) is able to sleep in a curled up position without feeling significantly cold.

And, for your information, the extreme temperature is the minimum temperature at which a person can survive (risk of hypothermia) for 6 hours. This is a safety measure, not a comfort measure.

And what is the limit temperature rating?

The protocol for measuring the thermal performance of a sleeping bag is to use a mattress with a thermal resistance corresponding to an R-value of 4.8.If you use a less insulating mattress, the thermal performance of your sleeping bag will be lower.

We therefore recommend that you use an insulating mattress for better thermal comfort.

Which mattress should I use this sleeping bag with?

Simply dress in light clothing (one layer, ideally merino wool, is sufficient).
Warm up your extremities with a hat, gloves, socks, and hand/foot warmers if necessary. 
Use a sleeping bag liner to optimize warmth and avoid washing your sleeping bag too often. Choose a mattress with good insulation (R-value > 3).
And here's a little tip: contract your muscles (70% of the energy consumed is converted into heat) and try to keep still—moving around too much will let in cold air.

Weight and dimensions of the MT 500 5°C Sleeping Bag

When hiking, you may get a tear in your sleeping bag! The good news is that it can be repaired.
We recommend using self-adhesive repair patches (ref: 8584596).

If you don't feel comfortable doing this yourself, we offer a repair service in our Decathlon stores and one of our specialists can apply a heat-bonded patch for you.

How to repair the MT 500 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 insulation is made from silicone-coated spiral fibres that are highly compressible and durable.
The trapped air makes the filling highly insulating and lightweight.

It stays warm even when wet.

Do you want to know more about the wadding?

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

Durability is calculated using the Martindale test according to ISO standard 12947-2. This test involves rubbing the bag’s material against another material to assess its abrasion resistance.

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