The Inferno singlehandedly saved one tester’s two-week trip to Mongolia’s Altai Mountains. “I was beyond chilled from the subzero temps all day, and this bag became my refuge each night,” she says. Credit the 800-fill, water-resistant goose down overstuffed into trapezoidal baffles: The offset walls of trapezoidal baffles keep down from falling to the end of the chamber when you rotate onto your side, nixing cold spots. The 4.5-inch-thick draft collar and 3.5-inch-wide draft tube—both of which are larger than standard—seal the deal.
Like the Editors’ Choice Award-winning Mountain Hardwear HyperLamina, the Inferno’s 33-inch center zip allows you to easily sit up and do tent chores without leaving the warmth of the bag, and it’s long enough to sufficiently vent on warmer evenings (we slept comfortably in the low 30s). The 64-inch shoulder girth accommodates a puffy if you’re a cold sleeper or gives you enough room to roll around if you have to hole up during an extended storm.
Water-resistant fabric protects the footbox and hood and kept frost and condensation-coated tent walls from chilling us. At less than 3.5 pounds and only 11 by 20 inches when stuffed, it’s very packable (and affordable) relative to others in its class.
