Details h2>Rab Women's Neutrino 400 Down Sleeping Bag The Rab Neutrino 400 is an incredibly lightweight down sleeping bag, filled with top quality 800 fill power Hydrophobic goose down. It's perfect for summer use, lightweight backpacking, mountain marathons, cycle touring or anytime when saving weight is paramount. It's still pretty warm though, with a Limit of Comfort rating of -3°C, and you can always boost that with clothing or a belay jacket. The Neutrino bags have a mummy taper shape that maximises warmth for minimum weight. This is the women's version, so it's a bit shorter than the mens and slightly wider at the hips. The bags are hand-filled in Derbyshire by our experienced fillers - some of whom have been with Rab for 20 years - what they don't know about down isn't worth knowing! Pertex Quantum inside and out keeps the shell weight to a bare minimum.
