The "Biopod DownWool Summer" is the perfect trekking and biking sleeping bag for the best vacation times from late spring to early autumn, offering an excellent balance of insulation, weight, and pack size.
Grüezi Bag says:
What sets this sleeping bag apart is its innovative insulation. You'll quickly notice the difference in a DownWool® sleeping bag – it keeps you from feeling too cold or too warm. It creates a dry body climate and evens out temperature fluctuations.
This is achieved through the innovative blend of natural materials, down, and wool. This combination is patented and acts as a light and natural air conditioning system. The DownWool® sleeping bag from Grüezi bag® offers significant advantages over pure down or synthetic sleeping bags:
· Nothing insulates as well as high-quality down due to its high insulation capacity with minimal weight.
· However, down only insulates when it's dry and fluffy. In increasing moisture, the fine branches of down collapse, causing it to clump and significantly reducing its insulating ability. Chemical treatments are often used to make down water-repellent. DownWool® makes these treatments unnecessary as wool naturally keeps down drier, preserving its insulating properties.
· Wool can absorb up to 30% of its weight in moisture through its capillaries and then release it to the outside to avoid evaporative cooling. This ensures effective moisture regulation and temperature control. Even when wet, wool retains its insulating properties like no other material. Wool naturally creates a comfortable microclimate due to its unique climate-balancing properties. Additionally, wool neutralizes unpleasant sweat odors.
Thanks to the unique properties of DownWool® insulation, your body can save some of the energy-consuming work of regulating body temperature. The saved energy is available for recovery during sleep.
The result is excellent insulation and a broad temperature range in which you can feel comfortable and sleep well. This makes DownWool® sleeping bags from Grüezi bag® popular all-rounders

Material & Construction
- Outer and inner fabric: Ultra-light, durable, and recycled 20 denier 380T nylon (100% polyamide), which feels incredibly soft, supple, and silky on the skin. Achieved by pulling the fabric over hot rollers to narrow the pores, making it downproof and impervious to clothes moths while remaining naturally breathable without the usual plastic coating. The pores do not clog, neither due to the biobased BeSoDRY-ECO impregnation nor the sustainable BEMACRON dyes. The outer material is windproof and highly water-repellent.
- Insulation: 445 g DownWool® consisting of 70% high-quality down (90/10 with a fill power of at least 650 cuin) and 30% mechanically refined wool.
- Material composition: Shell 100% polyamide, filling 70% down/30% wool - contains non-textile parts of animal origin.
- RDS-certified down (RDS CU 859743), mulesing-free European sheep wool.
- OEKO-TEX® STANDARD 100 certification for all materials used. This label for textiles tested for harmful substances guarantees that the product is safe for health.
- PFC-free: No perfluorinated chemicals are used
- The sleeping bags are equipped with a permanent water-repellent impregnation based on biobased raw materials (BeSoDRY-ECO).
- Colors: Selected BEMACRON dyes from the CHT Group are used. They are non-toxic for nature and meet both Cradle to Cradle requirements and the bluesign® standard.
