A premium, lightweight 4-season sleeping bag perfect for cold conditions.

The Rab Neutrino 400 Down Sleeping Bag is a 4-season sleeping bag for lightweight enthusiasts. The Neutrino 400 has 400g of high-quality 800FP RDS goose down hand-filled in chevron baffles with a boxwall construction which keeps weight to a minimum, prevents down migration and helps overall loft. The tapered mummy shape, large zipper baffles, and oversized draft collar trap heat and reduce unused space for drafts to circulate.

The fabric used in the Neutrino 400 is a 100% recycled polyamide and nylon mix that has a fluorocarbon-free DWR coating for water and wind resistance against morning dew and frost. If you're planning a lightweight trip in the colder months, add the Rab Neutrino 400 Down Sleeping Bag to your sleep system.
