Designed for alpine trekking, mountaineering, and lightweight backpacking, this high-performance down sleeping bag offers exceptional warmth-to-weight performance for cold mountain conditions. Filled with premium 800 fill power European goose down, it uses advanced L.O.F.T 3D™ baffle construction to prevent down migration and eliminate cold spots for more consistent warmth throughout the bag. The tapered mummy shape keeps weight and pack size low, making it ideal for multi-day hikes, alpine expeditions, and fast-moving spring ascents.

Built for comfort and durability in technical terrain, this lightweight sleeping bag combines durable 20D Pertex® Quantum fabric on the base and footbox with ultralight 10D Pertex® Quantum fabric on the upper sections for improved loft and compressibility. Longitudinal chest baffles help trap heat around your core, while sidewall baffles reduce pressure points and improve comfort for side sleepers. An insulated zip baffle, adjustable hood, down-filled collar, and anatomically shaped foot box all help retain warmth during cold nights outdoors.

Hand-filled in Derbyshire, UK, this hydrophobic goose down sleeping bag is designed for serious outdoor use while remaining highly packable for backpacking and travel. Rated with a lower comfort limit of 21°F / -6°C, it also features anti-snag YKK® zippers, a lightweight compression dry bag, and a water-resistant storage sack for convenient packing and storage.
