Rab Neutrino Pro 700 Sleeping Bag: 5F Down

We're braving the rocky terrain above treeline for a few nights, so the first thing we shove in the bottom of our backpacks is the Neutrino Pro 700 Sleeping Bag. Rated for comfort at temps as low as 5F, the 700 uses a close-fitting design and high-fill power down to keep us cozy under the icy mountain air. Pertex Quantum Pro fabric and hydrophobic down give us the confidence those tough elements won't interfere with our shuteye.
