The new Rab Neutrino -12°C Down Sleeping Bag is an ideal choice for your winter environment, thanks to the cleverly constructed down insulation. The 800FP down insulation ensures trustworthy warmth throughout the night, enhanced by the L.O.F.T 3D™ construction using helix shaping and funnel points to prevent down migration throughout the bag. The bag is protected by the Pertex® Quantum fabric making it ideal for mountain adventures. The adjustable hood means you can control how you trap heat at the top of the sleeping bag, adjusting to your preferred needs. This sleeping bag comes with a handy stuff sack so you can condense the sleeping bag down for carrying in your rucksack.
