Ultralight travel – for micro-adventures with comfort

This sleeping bag is perfect for anyone who wants to experience freedom and comfort with minimal weight. Whether bikepacking, hiking long distances, or enjoying relaxing nights in a mountain hut – this compact down sleeping bag offers exactly what you need: a comfortable sleeping climate with minimal weight and pack size. Ideal for warm nights under the stars, for tours with light luggage, or as an addition to your insulating layer in a tent.

Optimized for warm nights and minimalist travel

With a comfort range of around 12 to 14 °C, this ultralight down sleeping bag is ideal for warmer weather, tours with overnight stays in mountain huts, or as an emergency solution for spontaneous bivouacs. The high-quality duck down ensures reliable warmth and a pleasant microclimate – even after a long day in the saddle or on the trail. Thanks to its close-fitting design, your body heat is optimally retained without overheating.

Technology and equipment for demanding tours

The outer fabric is made from recycled Helium 20D with a PFC-free DWR finish – lightweight, wind-resistant, and breathable. Inside, the recycled Supersoft 20D fabric ensures a comfortable feel against the skin. The 90/10 duck down filling with a minimum fill power of 700 cuin guarantees reliable insulation while remaining lightweight. And best of all: the down used is DOWN CODEX® certified – ensuring the highest ethical and environmental standards.

Temperature range according to manufacturer

✅ Comfort temperature (T-Comf): +16 °C (Eddy's temperature recommendation for this model is 14–18 °C for hut tours, bikepacking tours and summer tours)
✅ Limit temperature (T-limit): 13 °C
✅ Extreme temperature (T-Extreme): +3°C

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.
