Excellent warmth even at low outside temperatures
Hervorragend warm auch bei tiefen Aussentemperaturen
Translated from German To the original

The sleeping bag gives excellent warmth. However, it is heavier and more expensive than other sleeping bags.

Der Schlafsack gibt hervorragend warm. Er ist jedoch schwerer und teurer als andere Schlafsäcke.
