Don't need the bulk of a full jacket, but still crave that warmth? Try these heated vests on for size. These battery heated vests use rechargeable batteries and come in both women's and men's styles. Have you noticed lately that, style-wise, the vest is back? Not the same vests we wore with our three-piece suits, these heated vests for men and women are worn under a jacket or just over your shirt or top, keeping you toasty in even the coldest office, warehouse, big box store or even outdoors. Puffy or sleek, perfect for layering, these vests can keep you warm in style.
