SKU: kingcamp-wheatland-450-3-in-1-sleeping-bag
Built for cold-weather camping and other outdoor overnights, this heated sleeping bag combines a three-layer design with graphene heating sheets in the lower layer for adjustable warmth. It can be used as a mat, envelope-style sleeping bag, or blanket, giving it flexibility when conditions or camp setup change. The bag includes three heat settings and temperature guidance for both the heated system and the sleeping bag itself, so users can match warmth to the night ahead. A zipper bag is included for transport, and the switch area is described as helping prevent light rain, though the heating sheet cannot be machine washed.
