Details Rab Neutrino Pro 600 Down Sleeping Bag The Rab Neutrino Pro 600 is a very warm down sleeping bag that keeps the weight to a minimum, filled with top quality 800 fill power responsibly sourced Hydrophobic goose down. This is an upgraded version of the standard Neutrino 600, 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 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.
