This athletic but stylish pullover jacket can be worn as a mid or outer layer. Featuring a two zone heating system targeting the back of the neck and the upper back, the patented Zero Layer® Heat System provides optimal heat transfer, penetrating heat deep in to your body’s core for a superior warming experience. A tri-level switch is built in to the jacket and allows you to choose between 3 heat settings.
The Thermal Half Zip is powered by 5 volt (1 amp output min.) USB powerbank battery that can be found at most retail stores.
