Grüezi DownWool-Hybrid Ice Extreme Sleeping Bag is the optimal sleeping bag with a perfect sleeping climate, specially designed for very cold winter tours down to -25°C.
The highly elaborate DownWool® Hybrid construction has been specifically developed for temperatures ranging from -2°C to -30°C. In this design, the high-quality 800+cuin RDS-certified goose down from Eastern Europe is enveloped by a layer of AlmWool to protect it from freezing moisture. Additionally, the wool regulates the sleeping climate inside the sleeping bag. The intricate construction with H-chambers and box chambers prevents the down from shifting and thus eliminates cold spots. In terms of the cut, we prioritise additional width over less weight, as this eliminates any cold bridges and allows the sleeping bag to realise its full insulation potential.
The Biopod DownWool® Hybrid has been developed for extreme cold, as evidenced by its use in Greenland or on Mount Aconcagua in Argentina. Even during a test in a cold chamber at -38.5°C, the sleeping bag remained pleasantly warm. Due to the fact that people can feel colder more quickly when exhausted or mildly ill, we recommend a sleep limit of -25°C.
An integrated carbon heating element in the foot area provides the necessary safety buffer in emergencies or illness. Numerous field tests in the Arctic, in high- altitude mountain ranges beyond 6,000 meters, as well as tests in cold chambers, have confirmed our concept.
FEATURES
Adjustable hood with Face Baffle: The thermal bulge adapts perfectly to the shape of your head. When it's cold, only a small hole remains open, reducing heat loss from the face.
3D thermal collar: Closes automatically in the zipper area so that no cold bridge is created in the zipper area.
Drawstring pocket: To ensure that the drawstring on the warm collar does not get in the way, it is safely stored in a simple drawstring pocket.
Inside & outside pocket: For valuables and things you prefer to keep close to you.
Two-way autolock zipper: The zipper can be opened and closed from either end, inside or outside. The auto-lock prevents it from opening accidentally.
White zipper: This makes it easier to find the zipper in the dark.
Zipper with anti-snag zipper and lined robust webbing: This makes it even easier to operate the zipper without pinching the outer fabric.
Zipper with underlaid Zipper cover: So that the heat cannot escape and no cold bridges are created.
Elaborately pre-formed foot box: With many chambers to avoid cold spots and plenty of room for the toes
Feater loops: The warming hip bag with heating element (Feater - The Feet Heater) can be installed additionally.
Chamber construction: Boxing chambers, H-chambers (V-shaped), additional Sidewall construction, AlmWolle layer construction on the top
Removable carbon heating element in the foot area: The heating element can be operated with a standard power bank (USB port is located in the inside pocket) and is washable at 30 °C.
Heating time: The heating element heats up to a maximum of 40°C to create an optimal comfort climate. It takes about 15-30 minutes to heat up, after which the sleeping bag stores the heat, keeping you warm all night long.
Info: The operating time of a power bank with 5.000 mAh is approx. 1,8 hours / with 10.000 mAh approx. 3,6 hours.
Anti-slip knobs on the back: They prevent the sleeping bag from slipping on an insulation mat.
