Product Info

Leveraging the incredible warmth-to-weight properties of down insulation, the Rab® Neutrino 400 Sleeping Bag offers standout sleep comfort with excellent packability. This midweight bag sits in a perfect middle ground for ultralight backpackers. It's warm enough for you to be prepared for any temperature you're likely to come across during the camping seasons, and that's it. No unnecessary insulation is added, and the tapered mummy shape keeps materials to a minimum. The result is a sub 2 lbs. bag that is ready for anything.
