Rab Neutrino 600 Sleeping Bag: 10F Down Nightfall Blue, Long/Left Zip

High warmth in a low-bulk, low-weight design may seem impossible, but Rab's Neutrino 600 Sleeping Bag surprises us. Designed with year-round alpine missions in mind, this sleeping bag is warm enough for wintry excursions without making us sacrifice space in our packs.
