| What is comfort temperature? |
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, 1.60 m) feels comfortable and not cold when they are in a relaxed position.
Choose your sleeping bag accordingly. |
| What is the temperature rating (lower limit at which you feel comfortable)? |
The limit temperature rating is the minimum temperature at which an average person (male, 25 years old, 70 kg, 1.73 m) is able to sleep in a curled up position without feeling significantly cold.
For your information, the extreme temperature is the minimum temperature at which a person can survive (risk of hypothermia) for six hours. This is a safety measure, not a comfort measure. |
| Which mattress should I use this sleeping bag with? |
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 reduced.
We therefore recommend that you use an insulating mattress for better thermal comfort. |
| How do you avoid feeling cold in your sleeping bag? |
- Warm up your extremities with a hat, gloves, socks and hand/foot warmers if necessary.
- Use a sleeping bag liner
-Choose a mattress with good insulation (R-value > 3)
- Tense your muscles before you go to bed |
| How to repair your 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.
We recommend using self-adhesive repair patches. |
