HEAT WHEN YOU NEED IT
For those super cold, sub-zero days, turn your jacket to High mode to stay warm at temperatures as low as -10° F (-23° C). If it becomes a chilly, 38° F (3° C) Fall evening, simply put the jacket into Low mode to stay comfortable. If you are out on the slopes, and it is getting cold on those lifts (15° F / -9° C), turn your jacket to Medium. And for those windy, 55° F (12° C) degree afternoons, just wear the light down jacket without turning the heating system on.
