extra warm hybrid sleeping bags

DownWool hybrid sleeping bags with Alpine wool and down

Sleeping bags for extreme cold with excellent sleeping comfort!

When temperatures drop well below 0°C, we rely on hybrid technology in our DownWool Hybrid sleeping bags. These sleeping bags are designed with an elaborate chamber construction, filled with high-quality goose down, and an additional layer of wool.

The wool layer on top of Grüezi bag® hybrid sleeping bags ensures that moisture inside the sleeping bag doesn't remain in the down, but is transported to the outer shell. This keeps the down dry and retains its high insulating properties. The heating element, which can be activated as needed, serves as a safety backup.
