Rab Neutrino -6C / 20F

The Rab Neutrino -6C is a high-performance sleeping bag precision-engineered for the dedicated alpine adventurer. Whether you are tackling long-distance treks or fast-moving spring ascents, its versatile all-mountain design balances weight and durability perfectly. The construction utilizes a dual-fabric approach to maximize efficiency: 20D Pertex® Quantum reinforces the base and footbox for protection against rough ground, while the ultra-light 10D Pertex® Quantum on the upper section allows for maximum loft and packability. This strategic fabric placement ensures a hardwearing bag that won't weigh down your pack during technical mountain pursuits.

At the heart of the Neutrino -6C is 800FP European Goose Down treated with a fluorocarbon-free hydrophobic finish to maintain thermal performance in damp conditions. Rated with a limit of comfort at -6°C, it is an ideal choice for three-season alpine use. Rab utilizes their pioneering L.O.F.T 3D™ construction, featuring helix-shaped baffles that eliminate cold spots and prevent down migration. Hand-filled in the UK to ensure the insulation is never over-compressed, the bag offers incredible warmth-to-weight efficiency. Longitudinal chest baffles further enhance heat retention by keeping the loft securely concentrated over your torso.

Functionality is central to the Neutrino’s design, featuring a tapered mummy shape and an anatomically shaped footbox for a natural sleeping position. Side-sleepers will appreciate the specialized sidewall baffles and internal cordlocks positioned below the collarbone to prevent irritation. The two-way YKK® anti-snag zip includes a full-length insulated baffle to lock in heat, while the snug down-filled neck collar and cinchable hood provide a protective seal against the elements. Complete with a lightweight dry bag for travel and a large storage sack for home, it is a masterclass in mountain-ready engineering.
