Rab Neutrino Pro 500 Sleeping Bag: 15F Down Granite, Long/Left Zip

Even during the summer, the temperatures can get drastic after dark, so we keep the Neutrino Pro 500 Sleeping Bag in our mountaineering kit for three-season comfort. The bag's narrow silhouette and chevron-shaped baffles keep pack weight as low as possible, while 800-fill down ensures we're as warm as can be once the sun goes down. Weather-resistant hydrophobic down and water-repelling recycled nylon prepare us for summer storms and high-mountain snow.
