Mummy sleeping bag
A mummy-shaped sleeping bag offers several advantages. The close-fitting shape means there is less room for air in the sleeping bag. You'll have the air that's in there up to temperature faster, making the sleeping bag warmer than a rectangular model. Also, most mummy sleeping bags come with a hood and a collar just above the shoulders that you can tighten. These features keep the heat trapped inside the sleeping bag and protect your head and neck, where you lose the most heat. The tapered shape reduces weight and volume in your backpack, bike pannier or car trunk.

Grüezi DownWool
The natural high-end DownWool-Insulation is a blend of 70% high-quality RDS-certified down, which provides high insulation, and 30% wool from the Alpine region, which acts like a lightweight natural air conditioner. The combination is perfect. Nothing insulates as well as high-quality down. The 30% wool content absorbs any moisture that arises and thus keeps the down naturally drier. Down has a very high insulating capacity at a low weight. However, down only insulates as long as it is dry and fluffy. With increasing humidity, the fine branching of the down collapses, which considerably reduces the insulating effect of the down. For this reason, the down is often treated with water-repellent agents. With DownWool, this is made unnecessary by adding the wool content. Wool can absorb up to 30% of its own weight in moisture without losing its insulating effect. Furthermore, wool is very temperature regulating and creates a pleasant microclimate in a natural way.

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 wide. This makes DownWool sleeping bags popular all-rounders.

Foot ventilation system
Thanks to the innovative foot ventilation system, you can place your feet comfortably on top of the sleeping bag to allow excess heat to vent.
