Why We Like The Rab Andes Infinium 1000 Sleeping Bag

Mountaineering missions in sub-zero temperatures are no joke—which is why we trust serious sleeping bags like the Rab Andes Infinium 1000 Down Sleeping Bag. Rated down to -20 degrees Farenheight, Rab's expedition-grade bag takes on extreme cold with a snug mummy shape that's stuffed with high-loft 800-fill goose down and lined with a heat-reflective titanium layer to limit radiant heat loss. That life-saving down is protected with a hydrophobic treatment and a GORE-TEX Infinium membrane with a durable water repellent to keep snow and moisture from compromising the insulating loft—or getting us wet. A down-filled neck collar, face baffle, and baffle over the zipper complete our protective cocoon, so we can conquer high-altitude routes in the Andes, the world's highest peaks, and arctic conditions.
