Lightweight sleeping bags

 

We give you an overview of lightweight sleeping bags that all are below 1.9 pund or 850 grams. In combination with a lightweight tent, chosing a lightweight sleeping bag will save you weight and space, so that you can pack all your hiking and camping gear in a 45 litre back pack instead of 60 litre.

EN13537: (from Wikipedia) EN13537 requires a thermal manikin test which produces four temperature results — upper limit, comfort, lower limit and extreme. These temperatures were worked for normal consumers.

 

The standard measures four temperature ratings:

 

Upper Limit — the temperature at which a standard man can sleep without excessive perspiration. It is established with the hood and zippers open and with the arms outside of the bag.
Comfort — the temperature at which a standard woman can expect to sleep comfortably in a relaxed position.
Lower Limit — the temperature at which a standard man can sleep for eight hours in a curled position without waking.
Extreme — the minimum temperature at which a standard woman can remain for six hours without risk of death from hypothermia (though frostbite is still possible).
For the purpose of these measurements, a "standard man" is assumed to be 25 years old, with a height of 1.73 m and a weight of 73 kg; a "standard woman" is assumed to be 25 years old, with a height of 1.60 m and a weight of 60 kg.
