Q. What does fleece mean in hoodies?

Answer

Despite being called after the recognizably furry coat on the sheep, the fleece definition specifies that the material is wholly synthetic and created from plastic ingredients. Rayon, one of the first synthetic fabrics, is still in widespread usage today. Nylon, developed by DuPont Chemicals in 1935, is a durable fabric that is also comfortable to the touch and simple to manufacture. Fleece hoodies, like any quality winter apparel, are very toasty. Fabric's "pile" texture helps trap heat next to skin and prevents chilly air from penetrating.
