Sleeping comfort, protection and climate – all combined in one sleeping bag

Do you want to sleep soundly even in the most adverse conditions – whether on a bushcraft adventure, bivouacking by a river, or on a damp boat? The Grüezi Bag Biopod Wool Survival is a true specialist for precisely these kinds of situations. This high-quality 3-season sleeping bag combines natural climate comfort with well-designed features for exposed nights in nature. Whether it's tropical humidity, uneven forest floor, or swarms of mosquitoes – with this outdoor sleeping bag, you've got everything under control.

Made for hunters, foresters, anglers and true outdoor survival fans

Whether you're sitting in a hunting blind during the colder months, spending nights in a high seat, on long expeditions in remote areas, or spending hours by damp water – this sleeping bag offers the warmth, quietness, and durability you need outdoors. Thanks to the resilient AlmWolle insulation, you'll stay dry and warm even in high humidity – even without a tent or in changeable weather conditions. The integrated mosquito nets protect against insects, and the compact pack size makes it easy to transport. For anyone who works outdoors or lives there, the Biopod Wool Survival is a reliable partner for cold nights in the field, by the fire, by the water, or under a tarp.

Sleep at your own pace – regardless of wind and weather

The comfortable cut of this wool sleeping bag allows you to move freely and sleep comfortably even on your side. The thoughtfully designed hood , a snug-fitting thermal collar, and a special foot ventilation system with mosquito netting ensure peaceful nights – whether you're sleeping in the middle of the forest, in a meadow, or by a lake. You can easily slide your feet out without being bothered by insects.

Integrated 3D mosquito net for maximum peace and quiet

A particularly clever feature: the 3D mosquito net in the head area can be easily attached with a zipper and effectively protects your face from mosquitoes, beetles, and other insects. The pop-up design ensures that the net doesn't rest against your face, allowing you to breathe freely. It's stored in a practical pocket directly inside the stuff sack – so you always have it with you when you need it.

Temperature ranges according to the manufacturer

✅ T-Comf: 4 °C (Eddy's temperature recommendation for this model is between 4 °C and 7 °C)
✅ Temperature limit: -1 °C
✅ T-Extreme: -17 °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 compresses at the back and therefore provides less insulation. A good sleeping mat is therefore essential for a warm night.

What makes AlmWolle so high-performing?

Made in Bavaria , lavalan® AlmWolle insulation relies on pure new wool from alpine sheep – natural, biodegradable, and sustainable. Wool is the only fiber that insulates even in high humidity, creating a consistently pleasant microclimate. It can absorb up to 30% of its own weight in moisture without feeling damp. Additionally, it is odor-resistant, antibacterial, and promotes a more restful, longer sleep.

✅ Dries quickly – ideal for use near water, in the tropics or in fog
✅ Acts like a natural air conditioner – protects against chilling and heat build-up
✅ Insulates even when wet – perfect for damp nights and wet clothes
✅ Neutralizes odors – no musty smell, even after several nights
✅ Supports regeneration – through consistent temperature and deep sleep

Who is this outdoor sleeping bag the right choice for?

Are you planning a microadventure, a canoe trip, or a bushcraft night in the woods? Are you a minimalist backpacker who doesn't want to sacrifice sleeping comfort? Then the Grüezi Bag Biopod Wool Survival is your ideal companion. It works reliably in tents, under tarps, or even without any cover – thanks to its well-designed features, robust materials, and breathable insulation.
