The NEWBULIG double multifunction sleeping bag redefines the outdoor sleeping experience. When fully expanded, it measures 90.55in × 61in and features professional-grade waterproof fabric and high-loft filling, achieving reliable warmth while maintaining a lightweight design. Its groundbreaking all-in-one design allows for quick conversion between a double sleeping bag and separate single sleeping bags through cleverly arranged zippers. The widened dimensions ensure comfort for two people, and the included two cotton pillows fit the head and neck contours. The intelligent temperature control system includes an adjustable hood and bottom zipper ventilation design, suitable for different seasonal needs. For safety, velcro straps prevent accidental opening and help retain heat. The convenient storage system makes outdoor preparation quicker and easier, with no complicated compression steps needed, and the sleeping bag instantly regains its full, fluffy shape when taken out. It is also machine washable, ensuring the sleeping bag always stays clean.
