Spindrift 850 Hyd-XT Gen 2 - Left Hand Zip Sleeping Bag

Description

The Mont Spindrift XT 850 is a high mountain sleeping bag built for serious winter camping, alpine climbs and ski touring, with an EN 13537 comfort rating of −13 °C and lower limit of −19 °C. Hydronaute XT shell fabric delivers a 20,000 mm water column and 20,000 g/m²/24 h breathability to manage frost and tent condensation, while 900+ fill-power down provides outstanding warmth-to-weight. A tapered mummy profile, differential cut and box-wall baffles eliminate cold spots and maximise loft. A full-length two-way YKK zip, down-filled draft tube and insulated collar seal in heat, and the 3D hood cinches snugly when the temperature drops. Pack it small for remote hut trips or multi-day snow camps and recover fast after big vertical days.

Despite expedition-ready warmth, the Spindrift XT 850 remains practical for varied Australian alpine conditions. The DWR-treated nylon lining feels comfortable against baselayers, an internal pocket keeps essentials handy and the included compression sack reduces bulk to a compact 21 × 28 cm. Ethically sourced down and durable construction make this a long-term winter partner for backcountry missions and cold-weather trekking.
