Sleep in the great outdoors with confidence, even in freezing temperatures, with The North Face Inferno 0F/-18C Sleeping Bag. Outfitted for extreme weather, it features a vaulted footbox and a side half zipper for temperature adjustments. Its recycled nylon body is not only light and durable, but also coated in aluminized Xreflex for superior thermal retention. The sleeping bag is designed with a full draft collar and integrated draft overlap for added comfort, while the waterproof Neovent Air fabric shields the head and footbox. The trapezoidal side-chamber baffles reduce cold spots and retain loft. Say goodbye to slipping sleeping pads thanks to shock cords and seal out the cold with the hood cinch cord.
