Take on cold-weather adventures with confidence using the ALPS Mountaineering Zenith 0° Sleeping Bag, a premium down mummy sleeping bag built for backpackers and campers who demand lightweight warmth and dependable performance. Rated to 0°F, the Zenith 0° is ideal for winter camping, shoulder-season backpacking, and cold alpine nights where reliable insulation is essential. Filled with hydrophobic down insulation, this sleeping bag delivers excellent warmth-to-weight efficiency while resisting moisture to maintain loft and thermal performance in damp conditions. The mummy-style design minimizes heat loss by contouring closely to the body, while the insulated hood, chest collar, and full-length zipper baffle work together to seal in warmth and prevent cold drafts. A durable 20-denier nylon shell and liner provide abrasion resistance without adding unnecessary weight, making this bag a strong choice for backcountry travel. When it’s time to pack up, the Zenith compresses efficiently into the included compression stuff sack for easy transport in your backpack. Whether you’re tackling winter trails, camping at elevation, or preparing for unpredictable cold nights, the ALPS Mountaineering Zenith 0° Sleeping Bag delivers lightweight packability, reliable warmth, and trusted performance for serious outdoor adventures.
