Engineered for three-season mountain environments and long-distance trail hikes, this technical sleeping bag blends durable, ultralight fabric with 800 fill power goose down to deliver first-class warmth-to-weight performance for mountaineers and trekkers who demand reliable protection for challenging environments.

How will some of the key features of the Rab Neutrino -6C/20F Ultralight Down Sleeping Bag enhance my experience?

Rab’s revolutionary L.O.F.T 3D Baffle Technology uses helix-shaped baffles to prevent down migration and maximise heat retention whilst compressing to minimal pack size for mountain efficiency. In addition, longitudinal chest baffles deliver increased thermal efficiency across your core, ensuring warmth where it matters most during cold nights. Furthermore, the anatomical hood with drawcord adjustment creates customised fit that maximises comfort whilst preventing thermal loss during active sleep movements. The sleeping bag also features strategically positioned internal cordlocks below the collar bone, ensuring greater side sleeping comfort without pressure points, whilst sidewall baffles increase down loft for enhanced thermal performance in lateral sleeping positions.
