Knitted fleece has little to do with its natural counterpart made of wool. Polar fleece, also known as polyester polar fleece, is a fabric made from extruded polymer fibers.

   This fabric is soft fleece and is known for its soft, felt or shaggy texture. While much lighter than wool, polyester fleece's fleece retains heat effectively and provides wool-like warmth and softness. Wool tends to be pill-resistant, which means the fabric is less likely to develop pilling or bumps with wear over time.

   The addition of cotton or other fibers and differences in manufacturing techniques can produce a wide variety of fleece fabrics, making it easy for designers to source the ideal fleece for a product.

   Clothing fashion designers or craft lovers might be better suited to describe the full range of products that can be made from polyester fleece fabrics.

   The quality of this fabric, as well as its durable and waterproof properties, make it ideal for the production of a wide variety of clothing and household items. Low maintenance costs and ease of use have made polar fleece increasingly popular and widely used in clothing, household items such as sweaters, scarves and baby clothing, blankets, and shirts.
