Happy's Warming Scarf with heat fusion is a simple way to stay warmer longer when exercising, running errands, or just traveling from place to place. Our unique grain filled quilted chambers allow you to heat your scarf in the microwave. The grain inside the chambers naturally retains heat and keeps you warmer longer. You will find the grain filled warming chambers around the neck area and inside the pockets of your Warming Scarf. Keeping your hands and neck warm is an integral part of keeping your whole body warm when exposed to cold temperatures.
