A sleeping bag stands for adventure, holidays, a break from everyday life. But we have to be able to rely on it completely in different conditions. So it has to be warm, but not make us sweat. Ideally, it should also be easy to care for. Quite a lot of requirements that the Grüezi Bag models fulfill without any problems. The innovative insulation made from down and wool is unique.
WHY Down in combination with wool?
Wool is a small miracle of nature. It regulates temperature, absorbs moisture without feeling clammy and is naturally antibacterial. Grüezi bag utilises precisely these properties in its DownWool insulation – a mix of 70 % down and 30 % wool. The result: the high thermal performance of down combined with the climate equalisation of wool.
DownWool really comes into its own in cold, wet conditions: While pure down quickly loses its insulating power when it gets damp, DownWool maintains its thermal performance. The wool absorbs moisture and thus protects the down – without any additional impregnation. This means that DownWool remains permanently efficient, even in high humidity.
💡 Fun Fact: Despite the wool content, the material weight of a DownWool sleeping bag is almost identical to that of a pure down model. A 3-season model only weighs around 30 grams more – a small surcharge for significantly more comfort.
