Based out of Michigan, the FNDN team knows how grueling the bitter cold winter weather can be. That’s why they designed the heated scarf to give comfort even in extreme cold weather conditions. Made from an ultra-soft chenille material, the FNDN heated scarf is powered by a rechargeable 3.7V Li-ion battery. Select your optimal level of warmth with three heat settings controlled by a simple push button. Perfect for outdoor activities, the heated scarf takes the pain out of cold weather commutes or walking your dog during the winter months.
