Sleep ultralight – with maximum comfort at minimal weight
When every gram counts, but you don't want to compromise on warmth, this down sleeping bag is perfect for your trip. Whether trekking , on multi-day mountain tours , fastpacking , or trail running with bivouac nights – this ultralight summer sleeping bag offers exactly what you need: reliable warmth, a small pack size, and outstanding comfort.
For sophisticated nights under the open sky
Weighing just 470 g (Regular), this sleeping bag is among the lightest in its class. Despite its light weight, it offers outstanding warmth, ideal for nights just above freezing. This is made possible by the high-quality 197 g fill of certified goose down (DOWN CODEX®) with over 900 cuin fill power. The PLASMA 10D outer fabric is not only exceptionally breathable but also water-repellent thanks to a PFC-free DWR finish. Morning dew or light moisture? No problem.
Sophisticated chamber design for maximum heat
Angled baffles at the top, vertical box baffles in the chest area, and quilted baffles at the bottom – this ingenious combination reduces cold spots while saving weight. The anatomically shaped, five-baffle hood and the three-piece foot section keep you comfortably warm from head to toe. The side zipper with the Gemini™ system provides additional protection against heat loss and is easy to use even in the dark.
Good Night's Sleep – comfortable even at 1 °C
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 scale according to the manufacturer
✅ T-Comf: 8°C (our recommendation for comfortable sleep is 9 °C - 12°C )
✅ Good Night's Sleep Temperature: 1°C/34°F
✅ Temperature limit: approx. 3 °C (limit for experienced sleepers)
✅ T-Extreme: down to -10 °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.
