High-quality 3-season sleeping bag

Grüezi bag® sleeping bags offer the best sleeping comfort and functionality
Grüezi bag sleeping bags have received numerous awards for their excellent insulation and well-thought-out designs.
-
DownWool® - the better down: Unlike conventional down, DownWool® retains its insulating properties even in high humidity of up to 90%. This means DownWool® offers better thermal performance, even in cold, wet conditions.
-
Wider temperature range: DownWool® sleeping bags have a wider temperature range in which you feel comfortable. Wool balances out temperature fluctuations.
-
Drier sleeping environment: The blend of RDS-certified down and 30% wool from the Alps in DownWool® sleeping bags creates a dry, balanced sleeping environment. Wool effectively wicks away moisture and provides warmth even when damp.
-
Best sleep quality: longer sleep, faster falling asleep and better sleep through the night, all thanks to the wool content in the DownWool® insulation filling
-
Well-thought-out cut for optimal freedom of movement: The comfortable cut allows the body to assume a relaxed position, ensuring a peaceful, restful sleep. Even in the mummy shape, you can sleep more soundly, as you can turn around both on your side with your leg bent and within the sleeping bag.
-
Avoidance of cold bridges: Our slightly wider cut reduces unpleasant cold bridges caused by compressed insulation
-
Lightweight and small pack size: ultra-light, robust and recycled materials save weight .
-
OEKO-TEX® STANDARD 100 certification: Grüezi bag® products are harmless to human health.
FEATURES
-
Pillow compartment: If you slide a fleece jacket, for example, into the pillow compartment, the sleeping bag has a non-slip pillow.
-
Adjustable hood with face baffle: The thermal baffle adapts perfectly to the shape of your head. When it's cold, only a small face hole remains open, thus reducing heat loss from the face.
-
3D thermal collar: Closes automatically in the zipper area, so there is no cold bridge in the zipper area.
-
Drawstring pocket: To ensure that the drawstring on the thermal 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.
-
Zipper
-
Two-way auto-lock zipper: The zipper can be opened and closed from either end, inside or outside. The auto-lock prevents it from opening accidentally.
-
White zipper: So you can find the zipper more easily in the dark.
-
Zipper with anti-snag zipper and lined robust webbing: This makes the zipper even easier to operate without pinching the outer fabric.
-
Zipper with lined zipper cover: so that heat cannot escape and no cold bridges are created.
-
Foot ventilation system: The innovative zipper design allows your feet to be comfortably placed on top of the sleeping bag and excess heat can escape.
-
Pre-shaped foot box: when lying down there is enough space in the sleeping bag to point your toes.
-
Feater loops: A warming hip bag with heating element (Feater - The Feet Heater) can be installed additionally.
-
Chamber construction: H-chambers, V-shaped (on the top), pre-shaped foot area with several chambers
-
Scope of delivery: sleeping bag, compression bag, storage bag.

WHAT IS DOWNWOOL®?
What makes this sleeping bag special is its innovative insulation: In a DownWool® sleeping bag, you immediately feel the wide comfort temperature range, where you're neither too cold nor too warm. The insulation is also naturally more resistant to high humidity.
This is achieved through a mechanical blend of 70% animal welfare-certified down (RDS-certified) and 30% wool from the Alps. This combination is patent-pending and functions like a light and natural air conditioner.
Down: excellent insulation performance
High-quality down provides exceptional insulation with low weight. However, down clumps in high humidity (air, sweat, condensation) and loses its insulating properties. Grüezi bag solves this issue with its innovative DownWool® insulation.
Wool: effective moisture and temperature regulation
Thanks to the addition of wool in DownWool®, the down stays naturally drier and retains its insulating ability. Wool can absorb up to 30% of its own weight in moisture through its capillaries and slowly release it back outside.
DownWool® remains insulating even at humidity levels of up to 90%. Wool fibers lift in humid conditions, increasing the insulation loft by up to 30%, which further enhances the sleeping bag’s performance.
DownWool® not only effectively regulates moisture but also your body temperature. Wool prevents cooling from evaporation and maintains its warming properties even when wet—something no other material can do. It creates a naturally cozy microclimate through its unique balancing effect.
The body requires a lot of energy to regulate its temperature. Wool supports this process through its outstanding temperature-balancing properties. Additionally, wool neutralizes unpleasant odors.
The result: Excellent insulation and a wide temperature range in which you feel comfortable and sleep well. Plus, DownWool® is less sensitive to moisture. This makes DownWool® sleeping bags from Grüezi bag® popular all-rounders.

CARE INSTRUCTIONS
Washing
- The washing instructions can be found in the sleeping bag’s inner pocket.
- The sleeping bag can be washed by hand or in a machine (wool cycle) at max. 30°C / 86°F using down detergent.
- Turn inside out, close all zippers, use an extra rinse cycle, and do not use fabric softener.
- Remove from the machine, loosen up slightly, and run a spin cycle at max. 600 RPM.
Drying
- Tumble dry at max. 60°C / 140°F, adding 2–3 tennis balls to loosen the filling.
- Repeat drying cycles as needed, removing the bag between cycles, shaking and fluffing it, and letting it cool briefly.
- Use a time-program to ensure the down fully dries.
- If no dryer is available, place the sleeping bag flat on a drying rack on sunny days and shake it out frequently to allow air to reach both sides.
When is it fully dry?
If it hasn’t regained its original loft, continue drying. The process may take at least 2 days, depending on outer fabric and dryer type.
Down must be completely dry—if not, clumping may occur, permanently damaging the bag.
You’ll know it’s dry when it feels fuller and fluffier than before. Any musty smell from damp down will disappear once fully dried.
TIP
- Dry your down sleeping bag with tennis balls in the dryer after each trip to remove excess moisture.
- Store sleeping bags open and dry in their storage sack.
- When packing into the compression sack, stuff the foot section first – do not roll or fold it.
- Air drying is better than washing. DownWool® sleeping bags rarely need washing, as wool naturally repels odors and dirt. For small stains, gently clean only the affected area. Wash only if heavily soiled.
- Always use a sleeping pad under your sleeping bag – insulation compresses underneath you and can’t retain heat without a pad. More on choosing the right pad can be found on the website here.
