Quick overview

Spring through autumn is the best season for trekking, biking, backpacking and camping. The 3-season sleeping Grüezi bag Biopod DownWool Subzero is the ideal companion here. Its comfortably cut mummy shape makes it light and packs down small. The pillow compartment is also very practical; just put a fleece jacket in here, for example, and you have a pillow that doesn't slip while you sleep. The mummy sleeping bag has an innovative zipper that allows you to comfortably put your feet on top of the sleeping bag when it gets too warm.

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.

DownWool® insulation

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.
