There are endless alpine landscapes waiting to be explored, and this is the sleeping bag to get you there. Offering outstanding warmth for weight with a robust, all-mountain design, it’s a versatile bag that easily adapts to a range of alpine pursuits, from long-distance treks to fast-moving summer ascents. We’ve strategically placed fabrics to give you maximum durability and loft where you need them, creating a hardwearing, hardworking bag that’s nonetheless super packable and lightweight. Filled with 800FP down in our groundbreaking L.O.F.T 3D™ baffle construction which eliminates cold spots, it provides the efficient warmth you need for technical pursuits on alpine terrain.

Hand-filled in the UK, all our down bags benefit from never having had their down compressed before use, preserving its loft and warmth.

• Pioneering L.O.F.T 3D™ construction features helix-shaped baffles that prevent down migration and maximise heat retention.
