Grüezi BagDownwool Summer Light 2.0 - Sleeping bag

Discover the Downwool Summer Light 2.0, a lightweight summer sleeping bag that combines comfort and innovation to offer you a restful sleep. Thanks to its unique DownWool® filling, this sleeping bag combines down and wool to ensure optimal warmth even in high humidity. Unlike traditional down, DownWool® retains its insulating properties even when humidity reaches 90%, ensuring consistent and pleasant warmth.

With a composition of 70% RDS-certified down and 30% wool from the Alps, DownWool® actively regulates body temperature to prevent overheating or excessive cooling. It absorbs and wicks away moisture, creating a dry and comfortable sleeping environment, perfect for changing climates. Its ergonomic cut offers optimal freedom of movement, even in mummy position, to prevent cold spots and ensure even warmth.

Lightweight and compact, the Downwool Summer Light 2.0 is certified OEKO-TEX® STANDARD 100, ensuring the absence of harmful substances for health. Ideal for hiking, camping, or staying in a refuge, this sleeping bag is your ally for peaceful nights from late spring to early autumn.

• Pillow compartment: If you place, for example, a fleece jacket in the pillow compartment, the sleeping bag has a non-slip pillow.

• Adjustable hood and its face baffle: The thermal bulge perfectly adapts to the shape of your head. In cold weather, only a small hole remains open, thus reducing facial heat loss.
