This is the breathable fleece scarf with three levels of heat to provide soothing warmth when cheering the team from the stands or gathering around the fire pit. Employing lightweight ultra-fine carbon fiber panels in an advanced heat-trapping insulation layer, it comfortably cuddles the neck and shoulders to provide over five hours of heat on low (125° F), over three at medium (135° F), and more than two at high (145° F). Water resistant to quickly shed rain, snow, or sleet to keep the wearer dry. With a 5-volt rechargeable battery. 100% polyester. Machine washable in the gentle cycle. Grey or Black. One size fits most.
