High-quality lightweight sleeping bag with Alpine wool filling for spring, summer and autumn. The Biopod Wool Zero XL is the allrounder of the Grüez-Bag Biopod series. Thanks to its Alpine wool filling, it offers an excellent climate and very good insulation values due to the second layer of Synthdown. Alpine Wool provides warmth and absorbs moisture. This creates an excellent sleeping climate. The sleeping climate is decisive for sleep quality. The deeper and more relaxed your sleep, the more rested you will be the next morning.
The Zero XL is lightweight and has a small pack size. Thanks to the extraordinary position of the two-way zipper on the Biopod Wool Zero XL, you can place your feet on the outside of the sleeping bag in warm nights, which is very hygienic. If you put, e. g., a fleece jacket into the pillow pocket, the Zero XL provides a pillow which does not shift. Ideal conditions for restful sleep.
