Inferno Sleeping Bag: -40F Down

This Inferno Sleeping Bag is The North Face's warmest expedition bag and is designed for the world's harshest environments. The North Face treated this bag's light and lofty 800-fill down insulation with ProDown water-resistance to retain its warmth in wet weather. Neovent Air fabric adds extra water-resistance to the hood, back, and footbox for moisture-riddled tents. A generous mummy cut helps you layer up before you go to bed, and the half-length center zipper offers easy entry. The North Face also added a cinch-cord at the hood and draft tubes at the collar and overlap to keep frigid winds at bay. This bag also features an internal pocket to insulate electronics and valuables.
