At just over two-and-a-half pounds light, the Mountain Hardwear Phantom 0 Degree Down Sleeping Bag takes a burden off our back and puts some Z's into our sleep. This ultralight mummy sleeping bag packs down small, fits our body like a glove, and features a water-repellent finish that fends off heat-robbing moisture so it can retain its loft and warmth. Lightweight, packable, and thoughtfully made, the Phantom is a welcome addition to your overnight kit whether you're headed out for a ski tour the next morning or setting up a vertical camp on a multi-pitch expedition.
