“This jacket is a light weight. My husband loves it. He says he is very warm and toasty. All you do is put the charger on to the battery, place battery in jacket, push the button by the collar and lights up red for warming, blue for cooling, and white to turn off soon.
My husband bought me one a couple years ago and I love mine! On the really really cold days I wear it and after a while I start to get really too warm.”
