The Domex Zenith is the ultimate all-weather sleeping bag for serious adventurers who demand warmth and performance in the harshest alpine conditions. With a Domex limit of -15°C, it’s purpose-built for mountaineering, winter camping, alpine hunting, and year-round use by cold sleepers who refuse to compromise on comfort. Engineered with premium 650+ loft hydrophobic duck down, the Zenith delivers outstanding thermal efficiency while retaining loft and insulation, even in damp conditions. Available in Standard and XT sizes to suit a wide range of body types, it combines technical innovation with practical comfort for dependable sleep when the mercury drops. The contoured mummy shape and spacious box foot are designed to maximise heat retention without sacrificing room to move. Smart vertical baffles across the torso and horizontal baffles through the legs ensure down fill stays evenly distributed, eliminating cold spots. A form-fitting 3D hood, insulated draught collar, and adjustable drawcord system lock in warmth around the head and shoulders, while the YKK ¾-length zip with dual sliders balances quick access with ventilation control on milder nights. Built tough with 20D/400Thd Ciré Ripstop fabric, the Zenith is highly durable, downproof, and water-resistant — a reliable companion for rugged backcountry use. It comes with a compression stuff sack for efficient packability, plus a large mesh storage sack to maintain down loft between adventures. Backed by a 5-year warranty, the Domex Zenith is the definitive 4-season sleeping bag for Australia’s alpine landscapes and extreme cold-weather expeditions.
