Details Rab Neutrino Pro 400 Down Sleeping Bag The Rab Neutrino Pro 400 is an incredibly lightweight down sleeping bag, filled with top quality 800 fill power responsibly sourced Hydrophobic goose down. This is an upgraded version of the standard Neutrino 400, with a Pertex Quantum Pro water-resistant outer shell, making it better for alpine bivis and general mountain use. The Neutrino bags have a mummy taper shape that maximises warmth for minimum weight. The bags are hand-filled in Derbyshire by 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 keeps the shell weight to a bare minimum.
