Features

Dress lightly (1 layer of clothing, ideally made from merino wool).
If needed, wear a hat, gloves, and socks, and use hand warmers. 
Use a sleeping bag liner to keep heat in. Avoid over-washing. Choose a mattress with good insulation (R-value >3).
Tip: contract your muscles (70% of the energy consumed is converted into heat), but avoid moving as this can create a draft.

How can I keep warm in the MT 500 Sleeping Bag?

Your sleeping bag may tear on a hike. It happens! The good news is that it can be repaired.
To do this, we recommend that you use self-adhesive repair patches (ref: 8584596).

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

How to repair your sleeping bag

We use 3 layers of overlapping fill:
- two layers of 115 g/m2, 100% polyester
- one layer of 100 g/m2, 100% polyester

The wadding 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 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.

How durable is fabric of the MT 500 Sleeping Bag?

All our sleeping bags display the temperature ratings tested by an independent lab (AITEX), in accordance with ISO 23537-1 standard. 
The comfort temperature is the lower limit at which the user is in general thermal equilibrium, feeling neither too cold nor too hot (for an average person in normal conditions).

Use this rating to choose the right sleeping bag for you.

What is the comfort rating?

The comfort temperature is the lower limit at which the user is in general thermal equilibrium, neither too cold nor too hot (for an average person in normal conditions of use).

What is the lower temperature limit?

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 when using a less insulating mattress, the thermal performance of your sleeping bag will be lower.

Use an insulating mattress to optimize your thermal comfort.
