    such a great idea!

    We got this for our son to have when she is active outside in our cold state of Mi. He is in kinder and has two recesses at school as well as several outside field trips. last week he had this vest on and felt perfectly warm the entire two hours in 38 degree weather. A great idea and I am so glad we bought it for him!

    Keeps My Son Warm

    The heated vest is perfect for a fall day. As soon as my son received the vest he wore on a cold breezy day and the jacket kept him warm. Battery pack and UBC wire included and the jacket has a custom inside pocket for the battery.
