Rab Neutrino Sleeping Bag: 20F Down

What Our Gearhead® Experts Are Saying:"I used this on a spring alpine trip where I was counting grams for the approach, and it barely registered in my pack weight while still keeping me comfortable overnight. The compression sack shrinks it down small enough that I had room to spare for extra food."Shoulder season trips reward whoever packs the smartest, and the Neutrino 20F Down Sleeping Bag is built for exactly that calculation. 800 fill power goose down delivers real warmth without adding grams, so it disappears into a pack until the moment it's needed at camp. Zoned L. O. F. T 3D baffles keep insulation evenly distributed rather than letting it bunch up overnight, while longitudinal chest baffles add extra warmth right at the core. The tapered mummy shape trims excess material for a lighter, more efficient build, and a lightweight dry bag compression sack squeezes the whole thing down small enough to leave room for everything else on the approach.
