Polar fleece

Polar fleece is a soft napped insulating synthetic wool fabric made from PET. It was created in 1979 by Malden Mills; it was a new, light and powerful pile fabric meant to mimic and in some ways surpass wool. Polar Fleece has some of wool's finest qualities but weighs a fraction of the lightest available woolens. The creators, Malden Mills, named it "Polar Fleece", never suspecting that they were coining an industry-household word. Polar Fleece garments are great addition to corporate clothing or promotional clothing range

As of 1998, only the following companies manufactured Polar Fleece in America: Malden Mills, Dyersburg Corporation (leader in polar fleece manufacture today), Menra Mills, Huntington Mills, Siltex Mills and Glenoit Mills.
