Rab Neutrino 400 Sleeping Bag: 20F Down in Nightfall Blue - Size: Long/Left Zip

Mountaineers and trekkers alike revel in comfort when the Neutrino 400 Sleeping Bag is our blanket for the night.

Rab designed it with a high-loft down that delivers a whopping wall of heat when the chill tries to bite its way in.

And to prevent any cold penetration, the Neutrino is built with chevron-shaped and trapezoid box-wall baffle construction.

Plus, a tapered mummy design and angled footbox design let us slip into a more natural position, ensuring we're comfortable at all hours of the night.
