Neutrino 800 Sleeping Bag: -5 Degree Down

Exploring high altitudes isn't always a comfortable pursuit, but after long days of ice-climbing, ski-touring, or general mountaineering, you can rest assured that at least one part of your day will be cozy with the Rab -5 Degree Down Neutrino 800 Sleeping Bag. It's filled to the brim with toasty 800-fill down, giving you warmth for high altitudes and cold temperatures without adding a ton of weight. Plus, it's got a special hydrophobic treatment that allows your down to maintain its loft in wet conditions. That means that not only will your bag keep insulating if it comes into contact with some snow or ice, but it will also retain its warmth when you're camping in wet-cold environments. A weather-resistant Pertex Quantum shell and a dry-bag stuff sack offer further protection from the elements while the bag sits in your pack, and a special trapezoidal baffle construction ensures that you won't suffer from cold spots due to down migration.

  • Lightweight sleeping bag for trips to high altitudes and cold temps
  • 800-fill down provides an excellent warmth-to-weight ratio
  • Hydrophobic treatment keeps insulating when you camp in the wet cold
  • Pertex Quantum fabric offers durability for rugged environments
  • Special baffle structure prevents cold spots cause by down shift
  • Mummy shape with drawcord hood provides snug coverage and warmth
  • Dry bag stuff sack keeps your bag dry on rainy backpacking treks
  • Internal 3D collar stops cold from creeping in the zipper
  • Item #RAB00L5

Not very warm

Took it out in 12F weather using an OR Alpine Bivy. The sleeping bag was not up too the task. More of an alpine summer bag. It is light and compact, but for warmth I have had better luck with a $36 ozark trail 10F bag. Very disappointed. Do not recomend

Usually warm(ish)

I've used it several times
True to size

The first few nights I used this bag when it was above freezing and it was amazing, so I was very excited. It's quite lofty but can pack down tight, which I appreciated. As soon as it started dropping below freezing, however, I noticed there was a draft all along the inside of the zipper and spots where down was not in the body of the sleeping bag. I was extremely cold in 20-25°F weather, despite wearing multiple layers of wool, sleeping on two insulated sleeping pads, and having a silk sleeping bag liner. One night it got down to 19° and I actually could not feel my feet, although I had thick wool socks on and other warm clothing inside the bag. Not sure if my body is dysfunctional or the sleeping bag is.


What is the length of this bag?
