High-quality sleeping bag for use down to freezing point
The "DownWool Ice 2.0"-Sleeping bag is the ideal companion for trekking, camping and mountain tours down to freezing point or as 3-season sleeping bag for the cold.
DownWool® 2.0 – the better down
The problem with classic down: moisture & overheating
Down is the lightest and most insulating natural material—and extremely compressible. However, traditional down has its weaknesses: it loses its insulating properties in high humidity and can lead to overheating. This poses a real risk to comfort and rest, especially when traveling in changeable climates. This is precisely where DownWool® comes in—the intelligent evolution of down. The award-winning DownWool® sleeping bags are uniquely designed and offer solutions for precisely these weaknesses.
-
Heat output even at high humidity
Unlike conventional down, DownWool® retains its insulating properties even in high humidity—and even increases them by up to a third. DownWool® puffs up, trapping even more warmth. Even at 90% humidity, it remains pleasantly warm—ideal for both dry and cold, wet conditions. -
Effective temperature compensation – no heat build-up, no freezing
The innovative filling consists of 70% RDS-certified animal welfare down and 30% wool from the Alps – a natural combination with high-tech functionality. DownWool® actively regulates temperature, constantly returning to skin temperature. This prevents overheating and avoids overcooling. At the same time, it absorbs moisture and wicks it away. This creates a pleasantly dry sleeping environment and a significantly wider comfortable temperature range – ideal for changeable weather. -
Comfortable cut – more freedom of movement, less cold
For restful sleep, the body needs freedom of movement. The ergonomic cut of DownWool® sleeping bags offers just that: space for sleeping positions such as side sleeping or turning, even in a mummy position. The slightly more generous fit prevents cold spots because the filling is not compressed – for consistently pleasant warmth and maximum sleeping comfort. - Best sleep quality: The natural climate-balancing insulation contributes to falling asleep faster, sleeping more deeply and overall longer, more restful sleep.
- And best of all: light & compact. In addition to their high functionality, DownWool® sleeping bags are amazingly light and packable – for more space in your backpack and maximum comfort on the go.
- OEKO-TEX® STANDARD 100 certified: Every part of the Grüezi bag® products has been tested for harmful substances and is therefore harmless to human health.

WHAT IS DOWNWOOL® 2.0?
DownWool® is the perfect combination of down and wool. This blend offers outstanding insulation and an exceptionally wide temperature comfort range – even in high humidity. This is made possible by the mechanical bonding of 70% RDS-certified down and 30% Alpine wool – a patent-pending, durable, and washable combination.
Down: best insulation performance
High-quality down offers excellent warmth with minimal weight. However, in high humidity (e.g., due to sweat or condensation), it clumps together and loses its insulating effect. This is where DownWool® 2.0 and solves this problem:
The added wool keeps the down drier, as it can withstand up to Absorb 30% of their own weight in moisture and can be released to the outside. Even with 90% humidity DownWool® remains insulating because the wool fibers stand up and the Increase bulking power by up to 30%In the latest DownWool® 2.0 blend, the wool has a down-like structure, resulting in even more loft and thus insulation.
In the latest DownWool® 2.0 blend, the wool takes on a down-like structure, resulting in even more loft and therefore insulation.

MAINTENANCE
- Article on the left turn around, zipper shut down.
- Fill the washing machine only half and choose a low spin speed.
- Wash your DownWool® products at 30 °C (86 °F) in the wool wash cycle of the washing machine or by hand – and only with down detergent and no fabric softener.
- Run an additional rinse cycle.
- After loosen slightly and again at max. spin at 600 rpm.
- For stains (e.g. deodorant residue or cream): Carefully knead the stain with diluted down detergentDo not rub! Clean the stain locally; complete wash only for large areas of soiling.
Drying Solutions
- In the tumble dryer at max. 60 °C / 140 °F, with 2–3 tennis balls.
- Multiple runs in the time program necessary.
- After each round: shake, let cool.
-
Without dryer: Let the DownWool® products Dry lying on a clothes rack in the air – not hanging, not on the heater and not in direct sunlight. Shake frequently!
When is the drying process completed?
- Until the item feels more filled than beforeIf the item still hasn't regained its original thickness, you'll need to repeat the drying process. Depending on the water resistance of the outer material, the drying time can vary (at least 2 days, depending on the dryer model).
- The down must be completely dry. If the sleeping bag isn't properly dried and fluffed, the down feathers can clump together, rendering the sleeping bag irreparably damaged. You can tell if the product is completely dry by whether it feels fuller and thicker than before. Damp down can have an odor, which disappears once it's dry.
TIPS/NOTES
- After each tourDown items should be dried in a tumble dryer with tennis balls from time to time or after every trip to remove excess moisture.
- Airing instead of washing: Wool doesn't need to be washed often. Airing the wool product thoroughly is usually sufficient—because wool is naturally odor-inhibiting and dirt-repellent.
- Occasional down feathers escaping These are normal and not a quality defect. Our DownWool® products are made from high-quality, intentionally uncoated fabrics to ensure breathability. Therefore, down may escape more easily than with coated fabrics. This phenomenon occurs only rarely and to a very small extent, and does not lead to any significant loss of filling or warmth.
- Store loosely and dry in the storage bag (not in the compression sack). When packing: Stuff the foot section first., do not roll or fold.
- Every sleeping bag needs a sleeping pad, because the insulation is compressed towards the bottom of the sleeping bag and therefore cannot retain air and therefore heat. You can find more information about the right sleeping mat here. here.
