Bivy life.

When you're hanging 150 feet up off the side of a rock wall, crawling into the Rab Neutrino Endurance 200 32-Degree Down Sleeping Bag for the night brings new meaning to the phrase "sleeping on cloud nine." Built to endure cool nights spent snoozing in an alpine bivy, the Neutrino Endurance 200 equipped with 800-fill hydrophobic down that retains its loft when exposed to moisture, both water vapor you generate from within and condensation from without.

The Neutrino Endurance's outer fabric consists of a rugged Pertex Endurance textile, which is treated with a breathable yet weather-resistant coating that prevents precipitation from getting the best of your beauty rest, while the interior fabric is composed of a durable yet lightweight Pertex Quantum layer that encourages ample breathability. In addition to its hardy exterior layers, this sleeping bag is equipped with a PrimaLoft Gold-insulated draft tube, trapezoidal baffle construction, and an angled footbox. You can attribute your sending-day success to all these features, because after all, sleep matters.

Hand Filled in Derbyshire

Sleeping bags are firmly where we started and they remain a core part of our range to this day. Back in the 1970's when Rab Carrington was making sleeping bags in Patagonia, he probably didn't imagine that 40 years later sleeping bags with his name on them would be used all over the world in some of the most beautiful yet hostile environments.

To this day, we hand-fill our down insulated sleeping bags at our factory in Derbyshire, UK. This allows us to know for definite that, by the time our bags reach our customers, they have never been compressed or stored in a way which could be harmful for the down inside. By filling the bags in house, we can be completely sure that every down sleeping bag that leaves our factory will arrive to our customers in the best possible condition.
