Ultralight, uncompromisingly warm – your down sleeping bag for real winter adventures
If you're out and about in freezing temperatures and every gram counts, this ultralight winter sleeping bag is your perfect companion. Designed for demanding mountain tours, multi-day winter hikes, high-altitude trail running adventures, or long autumn treks – this high-quality down sleeping bag offers maximum insulation at minimal weight. Ideal for anyone who doesn't want to take any chances when it comes to a warm night in a tent or under the stars.
Maximum heat output at minimum weight
Weighing in at just 690 g (size Regular), this down sleeping bag is among the lightest in its class – without compromising on warmth. This is made possible by the 373 g of certified European goose down (DOWN CODEX®) with an impressive 900+ cuin fill power. This guarantees reliable heat retention even in freezing temperatures – and even when conditions outside are anything but inviting.
The breathable and ultralight PLASMA 10D outer fabric provides added comfort. It not only offers reliable protection against moisture thanks to its PFC-free DWR finish, but also contributes to exceptional packability. Ideal for those who think in terms of backpack size.
Well-designed construction for effective heat distribution
Angled down baffles on the top and vertical box baffles in the chest area prevent cold spots and allow for maximum down loft. Quilted baffles on the underside ensure lightweight construction and targeted warmth. A particularly clever feature: the ground-level seams on the sides effectively keep the cold out.
The anatomically shaped hood with five down chambers protects your head, while the four-chamber footbox keeps your feet cozy and warm even on freezing nights. The 140 cm zipper with Gemini™ system prevents heat loss and is designed to prevent snagging – even with cold hands.
Reliable heat even under real-world conditions
The "Good Night's Sleep" rating for a Mountain Equipment sleeping bag 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
Temperature values according to the manufacturer
✅ T-Comf: approx. -2 °C (Eddy's temperature recommendation for this model is -1 °C to +4 °C)
✅ Good Night's Sleep Temperature: -7°C/19°F
✅ Temperature limit: approx. -8 °C (limit for experienced sleepers)
✅ T-Extreme: down to -26 °C (emergency area, not a comfort zone)
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.
