Grüezi Bag Biopod Wolle Survival Sleeping Bag
THE ROBUST SLEEPING BAG WITH PROTECTION AGAINST ANNOYING INSECTS AND SMALL ANIMALS!
The “Biopod Wolle Survival” is a robust and moisture-resistant 3-season sleeping bag that can be used in many areas. We recommend it for outdoor adventurers who like to spend the night without a tent, even on boats, on lakes and river banks or in areas with high humidity.
A 3D mosquito net was integrated so that annoying mosquitoes and other creepy crawlies don't bother you: The net is stretched over the head using a pop-up arch and thus protects against small uninvited guests. The net is stored in the integrated pocket on the pack sack.
The Grüezi bag® brand focuses on the best sleeping comfort and functionality: the climate and cut have already received several awards, as the sleeping bag
- has a consistently pleasant sleeping environment;
- has a comfortable cut that ensures sufficient freedom of movement;
- is at the same time light and small in pack size.
HOW ALMWOLLE INSULATION WORKS
The lavalan® alpine wool used in Grüezi bag® sleeping bags creates a perfect microclimate, helping regulate your body temperature. Wool can absorb up to 30% of its own weight in moisture, gradually releasing it outward to prevent any chill from evaporation. This natural moisture control keeps you warm even when wet — a feature no synthetic material matches. Plus, wool’s climate-balancing properties help neutralise sweat odours, keeping the sleeping environment fresh.
By reducing the body’s effort to regulate temperature, AlmWolle insulation helps you conserve energy — so your body can focus on rest and recovery.
Grüezi bag® uses wool sourced from Alpine-region sheep — a robust, natural, biodegradable, and renewable material.

3D Removable Mosquito Net: A pop-up style net with arched rods keeps insects away from your face without resting directly on it — ideal for buggy environments.
