- 2 seasons (from late spring to early autumn) - mummy shape close to the body - mainly made from recycled polyester Many people reserve the use of sleeping bags for summer. We designed this sleeping bag to change that: the single-layer synthetic fibre filling of the lightweight Sioux 400 sleeping bag saves weight while still providing enough insulation for trekking and hiking in temperate climates. This way, the synthetic fibre wicks moisture, keeps you warm even when wet (unlike down), and dries quickly.
The mummy shape and anatomical hood trap heat and create a comfortable sleeping environment. Too hot? You can let excess heat escape by quickly using the two-way zip.
Even sleeping outdoors is no problem: the exterior material of the Sioux 400 sleeping bag features a water-repellent and dirt-resistant Eco Finish without PFC. But this lightweight sleeping bag is especially a result of our strong commitment to sustainability, as it is part of the circular economy concept VAUDE. The main materials, as well as the filling, are made from 100% recycled polyester.
It also stands out for its resource-efficient design, durability, and ease of repair. The Green Shape label from VAUDE guarantees an eco-friendly, functional product made from sustainable materials.
