Mountain Hardwear Phantom GORE-TEX Sleeping Bag: -40F Down

Designed for the nights adjacent to high-alpine summit bids and deep winter dawn patrols, the Phantom GORE-TEX Sleeping Bag defends us against brutal conditions. This bag features GORE-TEX WindStopper, which seals out the coldest winds and resists moisture to protect the insulation. Mountain Hardwear filled the Phantom with 850-fill goose down for effective, efficient insulation that clocks in at a surprisingly low weight. We appreciate the vertical sidewall baffles that maximize loft, and therefore warmth, while the winter mummy cut efficiently adds space for cold-weather gear storage and extra layers. A centered, half-length zipper makes sitting up and getting in and out a breeze, while an ergonomic draft collar works with the face gasket to ensure heat won’t escape at vulnerable points.
