Built for alpine trekking, spring mountaineering, and lightweight backpacking, this premium down sleeping bag delivers impressive warmth without adding unnecessary weight to your pack. Filled with 800 fill power European goose down and constructed with advanced L.O.F.T 3D™ helix-shaped baffles, it prevents down migration and minimizes cold spots for reliable warmth in changing mountain conditions. The tapered mummy shape improves thermal efficiency while keeping the bag compact and highly packable for technical outdoor adventures.

Designed for comfort and durability on demanding terrain, this lightweight sleeping bag uses 20D Pertex® Quantum fabric on the base and footbox for added abrasion resistance, paired with ultralight 10D Pertex® Quantum ripstop on the upper sections to maximize loft and compressibility. Longitudinal chest baffles help retain heat around your core, while sidewall baffles improve comfort for side sleepers and reduce heat loss along seams. An insulated zip baffle, adjustable hood, down-filled neck collar, and anatomically shaped foot box help maintain warmth during cold nights in the backcountry.

Hand-filled in Derbyshire, UK, this hydrophobic goose down sleeping bag is ideal for hikers, mountaineers, and backpackers looking for lightweight performance in alpine environments. Rated with a lower comfort limit of 21°F / -6°C, it also includes anti-snag YKK® zippers, a lightweight compression dry bag for travel, and a water-resistant storage sack for home storage.
