Fleece is composed of synthetic materials that have similar qualities as wool. Moreover, it is lighter than wool and can be made in many possible colors and designs. The polar fleece blanket is thicker than the Micro Fleece blanket. Some people are sensitive or allergic to wool but want a blanket with comparable softness and warmth, which makes fleece a suitable alternative.
