Rab Neutrino 400 Sleeping Bag: 20F Down - Women's Nightfall Blue, Reg/Left Zip

The Neutrino 400 Sleeping Bag is so lightweight that we've often had to double check and make sure we packed it. Sure enough, there it is in all of its 800-fill lofty glory, ready to cradle us in premium warmth once we reach our basecamp for the evening.
