When the forecast dips and the miles keep coming, the Alps Mountaineering Zenith 0º Sleeping Bag is built to hold warmth without weighing you down.
Designed for high-performance cold-weather camping and backpacking, this down-filled mummy bag seals in heat where it matters most. A contoured hood and tapered profile reduce heat loss, while an insulated chest and zipper baffle block cold air from sneaking in during the night. Hydrophobic down insulation maintains loft and warmth even in damp conditions, giving you confidence when temperatures fall.
Despite its cold-weather rating, the Zenith 0º compresses smaller than many comparable bags thanks to lightweight materials and the included compression stuff sack—leaving more room in your pack for the gear that gets you there. Offered in multiple sizes, it’s a reliable choice for shoulder seasons, high-elevation trips, and winter-ready adventures.
