Great for hunting, Friday night tailgating and more, the Heat Factory Battery Powered Hand Muff provides instant and long-lasting protection from the bitter cold. The angled openings make it easy to access and comfortable to use, while allowing your hands to STAY WARM® without being restricted by gloves. A rechargeable 5V power bank sits inside the insulated and fleece-lined interior, providing the portability needed for a quality heated product, while making its presence in the product almost unknown. The LED push button located on the front side of the hand warmer gives you friendly usability and complete control over the level of warmth desired (max 130 degrees). The enlarged front zippered pocket is perfect for holding loose items. The adjustable waist strap can adapt to all waist sizes, and the “push/clasp” buckle facilitates easy removal. The Heat Factory brand Battery Powered Heated Hand Muff is a perfect accompaniment to any outdoor activity.
