Part of Backcountry’s touring collection, the Murdock 850 Down Jacket is a midlayer informed by feedback from the most experienced Backcountry Gearheads. We know the intense cold inherent in setting the Wasatch’s skin tracks before sunrise—a day at the resort can't compare to skiing sans daylight—so the Murdock not only keeps us warm during these frigid dawn patrols, but also packs away without taking much room in our ski packs. Its down insulation has the highest fill rating in the puffy business, meaning you’d be hard-pressed to find an insulator that compresses better.
