Rab Neutrino -12C / 10F

Rab Neutrino -12C / 10F is a high-loft, cold-spot-minimising three season sleeping bag built to deliver exceptional warmth at a low carry weight. The tapered mummy shape, sidewall baffles, and heat-sealing hood and neck collar help conserve warmth during alpine bivvies, long treks, and technical mountain nights. A two-way zip adds quick ventilation control, while the strategically placed Pertex Quantum fabrics balance packability up top with extra toughness around the base and footbox.
