Rab Neutrino 0°C Sleeping Bag

Built for all-mountain adventures, the Neutrino 0°C Sleeping Bag offers superb warmth for its weight, making it ideal for trekking, summer alpinism, and multi-day expeditions. Packed with 800FP down and featuring Rab’s L.O.F.T 3D baffle construction, it eliminates cold spots while providing efficient insulation exactly where it’s needed.

The Neutrino is designed for comfort as well as warmth. Longitudinal chest baffles conserve heat around your torso, while sidewall baffles reduce pressure from seams, allowing you to sleep comfortably on your side. The anatomically shaped foot box supports a relaxed sleeping position, and the cinchable hood with a down-filled collar locks in warmth. A two-way zip lets allows for ventilation on warmer nights, ensuring comfort in any alpine conditions.

Fabrics are strategically placed to provide maximum durability and loft where it matters most, creating a hardwearing, high-performance bag. Constructed with 20D Pertex Quantum on the base and footbox, the Neutrino offers durable protection against rough ground, while 10D Pertex Quantum on the top enhances loft and packability. This soft, lightweight, and windproof fabric allows the down to fully loft, providing excellent insulation without adding bulk. Whether trekking in the Alps or tackling fast-moving summer ascents, the Neutrino down sleeping bag is a versatile companion that keeps you warm, comfortable, and ready for every alpine adventure.
