Natural sleeping bag
Alpine wool in the sleeping bag "the natural air conditioning"
The quality of sleeping bags with Alpine wool filling is based on the excellent material properties of Alpine wool. A sleeping bag made with wool is therefore easy to care for and robust, odorless, breathable, temperature-regulating, and protects against moisture. The Alpine wool sleeping bag offers the same benefits as Alpine wool.
The Alpine wool fiber – the all-rounder in the sleeping bag
A look through the microscope reveals how the climate-regulating effect of alpine wool is created. The wool is clearly visible, arranged in different layers. There is a lot of air between the fibers. This warms up due to the sleeper's body temperature and retains the heat. Therefore, anyone resting in the sleeping bag is completely wrapped in warmth by the alpine wool filling.
Wool fibers can absorb up to 30% of their own weight in moisture. They are surrounded by a water-repellent stratum corneum and feel
They don't feel damp even if they've absorbed a lot of water inside. The human body can lose up to half a liter of water while sleeping. Thanks to the special properties of the wool fiber, the Alpine Wool sleeping bag prevents a sleeper from waking up sweaty and damp. To prevent the sleeping bag from absorbing too much moisture, it features a 2-layer construction with two different material layers:
The inner layer against the body is made of Synthdown, a high-quality microfiber filling. The outer layer, which is in contact with the outside air, is Alpine wool. The Synthdown layer quickly wicks moisture away into the wool layer. While a pure microfiber filling can cause evaporative cooling due to moisture escaping, which can impair the warming effect, Alpine wool releases moisture slowly into the outside air. This maintains the protective warmth. Alpine wool and Synthdown are very lightweight fibers. Therefore, this construction is also very lightweight and easy to pack. Moisture is not only created in sleeping bags by the human body. The outside air can also cause problems in rain, fog, or high humidity. A down filling can be affected by consistently high humidity. It can absorb moisture, and the weight of the water causes the down filling to collapse and the feathers to clump together. Alpine wool, on the other hand, maintains its stable fiber structure even in humid outside air and feels dry even after absorbing a lot of moisture. The stability of the wool fiber makes the sleeping bag even more robust against the diverse stresses it can be exposed to while traveling, especially when sleeping outdoors. The sleeping bag retains its shape and its firm filling structure. Furthermore, wool fibers are almost impossible to burn. They require more oxygen to burn than the air we breathe. The outer filling of alpine wool prevents ignition. However, the outer fabric can melt, but this only reduces the risk. The so-called bioreactivity of alpine wool is beneficial for sleeping bag hygiene. Wool fibers have self-cleaning properties and are antibacterial. Odors are neutralized.
Features, care and useful information about the "natural sleeping bag"
The Alpine wool sleeping bag has a full zip closure, as shown in this picture:
This allows it to be fully opened. It can also be opened at the foot area to allow air to escape. A pillow compartment is built into the upper section. This can be used to store a fleece jacket, sweater, or other textiles as a pillow substitute. The sleeping bag is machine washable at 30°C on the wool cycle.
Because of the filling, only wool detergent should be used. In addition to all the advantages for the sleeping bag user, one final point should be noted: Alpine wool is a particularly sustainable natural material. It occurs naturally and does not need to be cultivated as a raw material. Using the Grüezi Bag wool sleeping bag helps conserve energy and environmental resources.
