THE COMFORT RANGE is based on the lowest temperature at which a ‘standard’ woman (25 yrs. / 60 kg / 160 cm) can expect to sleep comfortably in a relaxed position. This range ensures a comfortable sleep, also for inexperienced users.
THE LOWER LIMIT is based on the lowest temperature at which a ‘standard’ adult male (25 yrs. / 70 kg / 173 cm) can expect to sleep comfortably in a relaxed position. An experienced user can optimise the insulation qualities by his choice of clothing and further factors.
EXTREME is a survival only rating for a ‘standard’ adult woman. She can remain for six hours without sleep. Without risk of death from hypothermia, but with a risk of other damages to health (such as frostbite).
The outer shell material is sewn to the upper layer of Polyester fleece. Since this construction can lead to cold spots, we only use it in summer sleeping bag.
