The Patagonia Storm Shift Insulated Jacket is built for the days when the mountain throws heavy snowfall, wind, and the kind of cold that settles in by early afternoon. Underarm zip vents let heat escape on the hike to the sidecountry entrance, and the hip-length cut covers the lower back when reaching for poles or leaning into a turn. The PFAS-free DWR finish on both the shell and the stretch taffeta lining holds water off the surface without adding stiffness in sustained precipitation. What Our Gearhead(R) Experts Are Saying:"I trust this jacket when the storm rolls in and doesn't let up. The GORE-TEX ePE shell keeps the wet out through a full day of heavy snow, and the heavier insulated zones across the chest and back mean I'm still warm at the end of a long lift line."
