The clothes are made from a composite fabric made up of three quilted layers, including an outer shell made of cotton fabric; an inner core of polyester fiberfill imbedded with water absorbing polymer; and an inner liner fabric made with a microporous breathable film laminated to cotton or high-density nylon. When immersed in cold water for three to five minutes the inner lining acts as a conductor, pulling heat from the wearer. The garment retains its coolness without allowing any water to pass through. These product's cooling effects can last up to eight hours when utilized as an outer garment or up to four hours as an undergarment, depending on its end use application and the environment in which the garment is worn. The fabric features a patented fiberfill technology and absorbs a finite amount of water, making the clothing lightweight (the vest weighs 11 ounces dry and just four pounds once activated).
