The following is the product description from the official website: The "Back Cover & Warmer," which is based on the "Baku," a creature with a bellyband pattern, is a versatile item that can be used in any location. As a sunblock cover in the summer sun, and as a warmer on chilly days. It can be worn on both hands and feet. It's perfect for everyday use, as well as for outdoor activities such as mountain climbing and hiking, with a color variation that will stand out.
