With a weight from 450g and a compressed pack size starting from 13 x 17cm, i.e. only a hand full, it is the ideal summer sleeping bag for trekking, biking, camping and for the Way of St. James.

A deep and restful sleep is especially important after an active day. That’s why Grüezi bag sleeping bags have a more comfortable cut, while paying attention to light weight and small packing volume. A unique feature of DownWool sleeping bags is their innovative insulation: DownWool is natural insulation made from 70% down and 30% wool and combines the advantages of both natural materials. Very good insulation and a pleasant feel-good climate.

How the unique Downwool Insulation works
The natural high-end DownWool insulation is a mixture of 70% high-quality RDS-certified down, which ensures high insulation, and 30% wool from the Alpine region, which acts as a light, natural air conditioner. The combination is perfect. Nothing insulates like high-quality down. The 30% wool content absorbs moisture and keeps the down naturally drier. Down has a very high insulation performance with a low weight. However, down only insulates as long as it is dry and fluffy. With increasing humidity, the fine ramifications of the down collapse, which significantly reduces the insulating effect of the down. For this reason, the down is often treated with water-repellent agents. With DownWool, this is made superfluous by adding the wool content. Because wool can absorb up to 30% of its own weight in moisture – without losing its insulating effect. Furthermore, the wool is very temperature-regulating and naturally creates a cozy and pleasant microclimate.

The result is a unique sleeping climate, which means that the temperature range in which you feel comfortable and sleep well in a DownWool sleeping bag is particularly large. This makes DownWool sleeping bags popular all-rounders.

Tip
Down sleeping bags should be put in the dryer from time to time with tennis balls to remove excess moisture.
