Neutrino -6ºC Sleeping Bag

Designed for all-mountain adventures, the Neutrino -6ºC Sleeping Bag delivers exceptional warmth for its weight, making it a perfect choice 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.

Comfort is just as important as warmth in the Neutrino. Longitudinal chest baffles retain heat around the torso, and sidewall baffles reduce pressure from seams, allowing side sleepers to rest comfortably. The anatomically shaped foot box supports a relaxed sleeping position, while the cinchable hood with a down-filled collar locks in heat. A two-way zip lets allows for ventilation on warmer nights, ensuring you stay comfortable in a variety of 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, this lightweight, down sleeping bag is a versatile companion that keeps you warm, comfortable, and ready for every alpine adventure.
