Highest Heat Setting
The jacket offers four graphene heating zones—two on the front and two on the back— and three heating settings—120, 140, and 160 degrees. You can cycle between the heating settings by pressing the button on the front of the jacket shown in the picture. Unfortunately, only the two heating zones on the back and one on the front—the right one— worked properly, which resulted in the left side of my jacket being extremely cold the entire time.
