'>Back wrap heating pads are portable devices made of soft, flexible materials that can be wrapped around the lower or upper back. Often filled with materials that retain heat, such as rice or gel beads, these pads can be heated in a microwave or an electrical outlet to deliver soothing warmth. Unlike traditional heating pads, back wrap versions are designed to conform closely to the body's contours, ensuring that heat is evenly distributed and targeted to the areas that need it most.
