While “home” may resemble something more akin to a small, walled windbreaker floating 400-feet above the ground, the Rab Women’s 15 Degree Down Neutrino Endurance 600 Sleeping Bag is designed to provide creature-comfort warmth. Rated down to 15-degrees Fahrenheit, this women-specific, down-filled bag is ideal for for alpine climbs, winter expeditions, and the bivi-ledge life where cold temperatures are expected. Thanks to the Neutrino Endurance’s 800-fill down insulation, you’ll stay toasty warm when temperatures dip below comfortably cool. Going one step further, the down insulation features a hydrophobic coating that repels condensation and built-up perspiration from clumping together its lofty down clusters. The water-resistant Pertex Endurance and Microlight fabrics prevent outside moisture from seeping through and compromising the down’s heat-trapping loft, which is ideal for cold weather adventures when the weather can change in the blink of an eye. Close-fitting neck baffles and trapezoidal baffle chambers lock-in heat by eliminating cold spots resulting from the migration of down insulation.
