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.

FEATURES

• Pillow compartment: If you put a fleece jacket, for example, into the pillow compartment, the sleeping bag has a non-slip pillow.
• 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.
• zipper:
  • Two-way zipper: Can be operated from both ends and inside/outside.
  • Auto-Lock prevents accidental opening.
  • White zipper: easy to find in the dark.
  • Underlined Zipper cover prevents cold bridges so that heat cannot escape.
  • Zipper with anti-snag zipper and lined robust webbing: This makes it even easier to operate the zipper without pinching the outer fabric.

• Foot ventilation system: The innovative zipper design allows your feet to rest comfortably on top of the sleeping bag and excess heat to 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

Technical details

• Temperature range according to EN ISO 23537-1:
  T comf -8 °C (18 °F)  | Tlim -15°C (5°F) | T ext -37 °C (-35 °F)
  This official ISO standard allows for a comparison of sleeping bags across different manufacturers. Since personal sensitivity to cold and usage conditions vary considerably, we recommend not going below the comfort rating; sensitive individuals should even stay a few degrees above it.
