Mummy sleeping bag VAUDE Sioux 800 S II — recycled polyester, 2000×750 mm, for users up to 170 cm

VAUDE Sioux 800 S II is a mummy-style sleeping bag for adults made primarily from recycled polyester. With overall dimensions of 2000 × 750 mm it is designed for users up to 170 cm and targets three-season use from spring to fall. The bag features a two-layer synthetic insulation that prevents cold spots, a form-fitting mummy cut for high thermal efficiency, and a PFC-free water-repellent outer treatment. Lightweight and highly compressible, the Sioux 800 S II includes a contoured hood, thermal collar and an inner pocket for small essentials. The construction emphasizes sustainability: shell and fill are produced from recycled PET and the product follows VAUDE’s Green Shape principles.

Advantages

The two-layer Sensofiber Eco insulation offers consistent heat retention and fast drying performance, maintaining insulation even when damp. The mummy design reduces dead air volume to increase thermal efficiency while keeping weight and pack size low. The outer fabric is durable, breathable and easy to clean; it is treated with an eco-friendly water-repellent finish that avoids PFCs. Materials and construction focus on resource efficiency and lower CO2 impact by using recycled polyester yarns and recycled-fill fibers.

How to use

Unpack the sleeping bag and allow it to loft before use to restore insulation performance. For sleeping, place the bag on an insulating sleeping pad to reduce heat loss to the ground, position the contoured hood around your head and adjust the thermal collar as needed. Use the two-way zip to regulate ventilation or unzip fully for warmer nights. Store the bag loosely in a dry, well-ventilated place when not in use and compress only into the included stuff sack for transport.

Usage recommendations

For best thermal performance, pair the Sioux 800 S II with an appropriate sleeping pad rated for the expected temperatures and use a breathable liner if extra hygiene or warmth is required. Clean according to the manufacturer’s care instructions, avoid regular machine drying at high temperatures and repair small damages promptly to extend service life.
