Pack the Neutrino 600 when the route calls for real cold-weather sleep

What Our Gearhead® Experts Are Saying:

"I've used the Neutrino 600 on shoulder-season alpine routes where the forecast is always a guess. What keeps me reaching for it is that it actually compresses down to something reasonable for a 10F bag — and the Nikwax-treated down doesn't lose loft when things get damp overnight. The 3D draft collar makes a real difference at that temperature range. It's not an ultralight record-setter, but for the warmth-to-packability ratio you're getting, it's hard to argue with."

Nights above treeline have a way of turning cold fast, and a 10F bag that won't dominate your pack changes the calculus on what routes are worth attempting. Rab's Neutrino 600 Sleeping Bag is built around that idea — serious cold-weather capability compressed into a roll-top stuff sack that doesn't feel like a compromise.

The 800-fill RDS-certified goose down is treated with Nikwax's FC-free hydrophobic coating, which means the insulation holds its loft through condensation and the kind of ambient moisture that collects in a tent at altitude. The 20D Pertex Quantum shell repels surface moisture and resists punctures without adding unnecessary weight. A 3/4-length zipper keeps the footbox sealed and heat contained, and the internal 3D draft collar closes off the one place warmth consistently escapes. It stuffs down to under 16 inches, which leaves room in the pack for everything else the route requires.
