When ordinary insulation isn’t enough, the Electric Heated Sleeping Bag takes over. Powered by USB and featuring 4-zone rapid heating with three temperature settings (40°C / 45°C / 50°C), this mummy-style bag delivers active warmth on demand — rated for extreme conditions from -10°C to -35°C. Whether you’re camping in deep winter, working outdoors, or preparing for emergencies, this bag keeps you warm when passive insulation alone won’t cut it. The down-cotton mixture fill provides baseline insulation even without power, while the waterproof terylene shell protects against moisture and the elements. Fully unzippable as an electric blanket, with an internal storage pocket and a compact 37 × 20 × 20 cm packed size, it’s as practical as it is warm.
