Made for extreme cold – your sleeping bag for winter expeditions

If you're heading to polar regions, high mountains, or on a winter tour, you need a sleeping bag that provides reliable protection even under the most extreme conditions. This expedition sleeping bag was designed precisely for that purpose. It offers uncompromising warmth, high durability, and well-thought-out features that will keep you warm and safe even in temperatures far below freezing.

Maximum insulation thanks to high-quality duck down.

The DOWN CODEX™ certified duck down filling (90/10, minimum 700 cuin) offers exceptional warmth at a comparatively low weight. With over 1300 g of down fill and meticulously constructed trapezoidal and box baffles, heat is efficiently retained and cold spots are reliably prevented. You can rest assured that the warmth stays where it belongs – with you.

It reliably protects you from wetness and wind.

The DRILITE® LOFT™ outer fabric features a durable water-repellent finish while remaining breathable. This keeps you dry, even if condensation builds up inside the tent or you're bivouacking in the snow. Even after repeated use on expeditions or tours in challenging climates, the sleeping bag remains high-performing and protective.

Thoughtful expedition design for the toughest conditions

The so-called Expedition Fit gives you extra room for gear or insulating clothing without compromising warmth. The ergonomically designed five-chamber hood and the anatomically shaped six-chamber footbox ensure optimal insulation for your most vulnerable areas. The 140 cm zipper with Gemini™ draft tube minimizes heat loss when getting in and out. The innovative Lode Lock™ magnetic closure on the draft collar makes it easy and intuitive to use, even with thick gloves.

One special feature: T-Comf states in parentheses (Eddy's temperature recommendation for this model is -17 °C to -12 °C)

✅ T-Comf: -35°C (Eddy's temperature recommendation for this model is -20°C to -30°C)
✅ Temperature limit: -35 °C (limit for experienced sleepers)
✅ T-Extreme: -45 °C (emergency area, not a comfort zone)

The statement "Good Night's Sleep at -35 °C" is a manufacturer's recommendation – based on practical tests and experience – and complements the official EN 13537/ISO 23537 standard (T-Comf, T-Limit, T-Extreme).

What does this information mean exactly?
"Good Night's Sleep Temperature" = Temperature at which you can sleep comfortably without feeling cold – even with prolonged use or under real-world conditions such as:
✅ lightweight sleepwear
✅ thin sleeping mat
✅ possibly damp weather
✅ Fatigue or hypothermia due to daily stages

Note on temperature perception: The temperature ratings are provided by the manufacturer and are standardized. In practice, however, they can vary – especially if you are exhausted, hungry, or wet. The quality of your sleeping mat also has a significant impact, as down is compressed at the back and therefore provides less insulation. A good sleeping mat is therefore essential for a warm night.
