Fleece is a soft, fuzzy material that is used to make a variety of things. Fleece is a common alterative of wool. Fleece is often used to make sweaters, jackets, throw blankets, mittens, hats, scarves, and other garments to keep people warm. It is usually used for items that will provide warmth because it is durable, holds in warmth, and whisks away moisture. According to the website How Products Are Made, fleece has also been used in the suits of scuba divers, the underwear of astronauts, and the ear-warmers of calves that are born during the winter.
Fleece is made of polyester. It was first created in the 1980s at Malden Mills, a manufacturer that is located in Lawrence, Massachusetts. Polyester fleece became popular in the 1990s under the trademark names Polartec and Polar Fleece.
