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 high-altitude treks to rugged winter 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.
FEATURES:
- Longitudinal chest baffles provide an efficient way of conserving heat around your torso.
- Pioneering L.O.F.T 3D™ construction features helix-shaped baffles that prevent down migration and maximise heat retention.
- 20D Pertex® Quantum on the base and footbox for durability on rough ground, while 10D Pertex® Quantum on the top increases loft and packability.
- Sleep comfortably on your side thanks to the sidewall baffles, which reduce cold spots and ensure you’re not lying on a seam.
- Cinch in the hood to seal in the heat, while the down-filled collar sits snugly around your neck.
- Two-way zip provides ventilation when you need it, while the insulated zip baffle prevents cold spots when the temperature drops.
- Internal cordlocks positioned below your collar bone for greater side sleeping comfort.
